- Note on the port XCIN-XCOUT switch bit (CM04)
- Note on the XCIN-XCOUT on-chip feedback resistor select bit (CM12)
- Note on the port XIN-XOUT switch bit (CM13)
- Note on the Module Standby Control Register (MSTCR)
- Note on the Emulator specified High-Speed On-Chip Oscillator Control Register 0
- Note on the High-Speed On-Chip Oscillator Control Register 1 (FRA1)
- Note on the High-Speed On-Chip Oscillator Control Register 6 (FRA6)
- Note on the High-Speed On-Chip Oscillator Control Register 7 (FRA7)
- Note on the voltage monitor 0 reset
After changing the bit 4 (CM04) of the System Clock Control Register 0 (CM0 at address
00006h) to “1” (XCIN-XCOUT pin), do not set it to “0” (I/O ports, P4_3, P4_4). Otherwise,
the emulator cannot be operated normally.
The functions associated with bit 2 (CM12) of System Clock Control Register 1 (CM1 at
address 00007h) cannot be used. When writing to CM12, always be sure to write a “0”.
This bit reads as “0” when read out.
After changing the bit 3 (CM13) of the System Clock Control Register 1 (CM1 at address
00007h) to “1”, do not set it to “0”. Otherwise, the emulator cannot be operated normally.
This product does not support the module standby control register (MSTCR: 00008h).
Therefore each function of IIC bus, timer RD and timer RC cannot be stopped.
(EMFRA0), 2 (EMFRA2)
This product has the emulator specified high-speed on-chip oscillator control register 0
(EMFRA0 at address 00223h) and the emulator specified high-speed on-chip oscillator
control register 2 (EMFRA2 at address 00225h). When rewriting the high-speed on-chip
oscillator control register 0 (FRA0 at address 00023h), write in EMFRA0 register. And
when rewriting the high-speed on-chip oscillator control register 2 (FRA2 at address
00025h), write same value in EMFRA2 register. Note that the bit assignment and R/W
condition of both EMFRA0 register and EMFRA2 register are the same with the ones of
FRA0 register and FRA2 register.
Do not change the high-speed on-chip oscillator control register 1 (FRA1 at address
00024h) while using this product. If FRA1 register is changed, some parts of functions
cannot be operated normally.
This product does not support High-Speed On-Chip Oscillator Control Register 6 (FRA6:
address 0002Bh). If you read FRA6 register, an undefined value is read in. Do not
transfer the value to FRA1 register.
This product does not support High-Speed On-Chip Oscillator Control Register 7 (FRA7:
address 0002Ch). If you read FRA7 register, an undefined value is read in. Do not
transfer the value to FRA1 register.
This product does not support the voltage monitor 0 reset and the voltage monitor 0
circuit control register (VW0C at address 00038h).
Therefore, do not access the voltage monitor 0 circuit control register.
6 / 7
- Note on the voltage monitor 1 interrupt
- Note on the Port P2 Drive Capacity Control Register (P2DRR)
- Note on the UART1 Function Select Register (U1SR)
- Note on the voltage detection 0 circuit start bit (LVD0ON)
- Note on changing the count source protection mode after reset select bit (CSPROINI)
- Note on using the A/D conversion start trigger by Timer RD (complementary PWM mode)
- Note on using interrupts and changing an interrupt control register
- Note on access to the SFR area from the emulator debugger
This product supports only voltage monitor 1 reset, and does not support the voltage
monitor 1 interrupt. Therefore, when setting bit 0 (voltage monitor 1 interrupt/reset enable
bit: VW1C0) of the voltage monitor 1 circuit control register (VW1C at address 00036h) to
“1”(= enable), always make sure that bit 6 (voltage monitor 1 circuit mode select bit:
VW1C6) is also set to “1”(= voltage monitor 1 circuit reset mode).
Be aware that the Port P2 drive capacity control register (P2DRR at address 000F4h) in
this product is subject to limitations that although the drive capability of the n-channel
(Low side) output transistor can be increased, that of the p-channel (High side) output
transistor cannot be increased.
When writing to the bit0 and bit1 of the UART1 Function Select Register (U1SR: address
000F5h) by using this product, always be sure to write “1”. When reading the value, “1” is
read out.
The function of bit 5 (LVD0ON) in the option function select register (OFS at address
0FFFFh) cannot be used. When writing to this register, always be sure to set LVD0ON to
“1”.
When you change the bit 7 (CSPROINI) of the option function select register (OFS at
address 0FFFFh), by rewriting directly in the memory window or downloading, the reset
operation from the emulator debugger should be done twice or more. Otherwise, the
alteration may not be reflected.
This product does not support the function of setting the bit 5 (A/D conversion trigger
select bit: ADCAP) of the A/D control register 0 (ADC0N0 at address 002D6h) to “1”
(starts at timer RD with complementary PWM mode). The usable A/D conversion trigger
in this product is only software trigger which sets ADCAP bit to “0”.
With the following registers, if an interrupt request corresponding to a register is
generated while executing the AND, OR, BCLR and BSET instructions that change any
bit other than the IR bit, the IR bit is not set to “1”(interrupt requested), and the interrupt
request is ignored. This behavior is different from the actual MCU.
Applicable registers: Compare 1 Interrupt Control Register
In the memory window, ASM watch window and script window of the emulator debugger,
if you reference or modify the SFR area in word unit, all the areas will be accessed by
byte except for some areas of the timer RC related registers (00126h--0012Fh).
Note that the SFR area can be accessed from the user program, as specified in the
program.
