(6) R8C/24 and /25 Groups
- 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 voltage monitor 0 reset
- Note on the voltage monitor 1 interrupt
- Note on the Port 2 Drive Capability Control Register (P2DRR)
- 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 access to the SFR area from the emulator debugger
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 voltage monitor 0 reset and Voltage Monitor 0 Circuit
Control Register (VW0C at address 00038h).
Therefore, do not access the Voltage Monitor 0 Circuit Control Register.
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 2 Drive Capability 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.
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 or downloading, the reset operation from the
emulator should be done twice or more. Otherwise, the alteration may not be reflected.
Note that the SFR area can be accessed from the user program, as specified in the
program.
In the memory window, ASM watch window and script window of the emulator debugger,
if you reference or modify the SFR area in word, all the areas will be accessed by byte
except for some areas of the timer RD related register (00146h--0014Fh,
00156h--0015Fh).

- Note on holding the error flags in serial interfaces
- Note on the High-Speed On-Chip Oscillator Control Register 4 (FRA4) and High-Speed
- Note on the High-Speed On-Chip Oscillator Control Register 7 (FRA7)
The clear conditions of the overrun error flag (OER) when using the clock synchronous
serial I/O mode and the clock asynchronous serial I/O (UART) mode, and the framing
error flag (FER) and the parity error flag (PER) when using the clock asynchronous serial
I/O (UART) mode are different form the actual MCU.

On-Chip Oscillator Control Register 6 (FRA6)
This product does not support High-Speed On-Chip Oscillator Control Register 4 (FRA4:
address 00029h) and High-Speed On-Chip Oscillator Control Register 6 (FRA6: address
0002Bh). If you read FRA4 or 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.
