ML610Q428/ML610Q429 User’s Manual
Appendix E Check List
Appendix E
Check List
This Check List has notes to prevent commonly-made programming mistakes and frequently overlooked or
misunderstood hardware features of the MCU. Check each note listed up chapter by chapter while coding the program or
evaluating it using the MCU.
Chapter 1 Overview
[ ] Please confirm how to handle the unused pins(Refer to Section 1.3.4 in the user’s manual).
Chapter 2 CPU and Memory
• Program Memory size
[ ] 48,128, Byte (0:0000H to 0:BBFFH)
• Data RAM size
[ ] 3072 Byte (0:D800H to 0:E3FFH)
• Unused area
[
] Please fill test area 0:BC00H to 0:BDFFH with BRK instruction code “0FFH” (Refer to a startup file
“S61043XSW.asm” for programming in the source code).
[ ] For fail safe in your system, please fill unused program memory area (your program code does not use) with BRK
instruction code “0FFH”. We will fill the area with the code “0FFH” at Oki semiconductor’s factory programming.
• Initializing RAM
RAM. Please initialize RAM by the software.
[ ] The hardware reset does not initialize
Chapter 3 Reset
• Reset activation pulse width
[ ] Minimum 200us (Refer to Appendix C-2 in the user’s manual)
• Power-on reset occurrence power rising time
[ ] Maximum 10ms (Refer to Appendix C-2 in the user’s manual)
• Reset status flag
[ ] No flag is provided that indicates the occurrence of reset by the RESET_N pin (Refer to section 3.2.2. in the user’s
manual).
• BRK instruction reset
[ ] In system reset by the BRK instruction, no special function register (SFR) is initialized either. Therefore initialize the
SFRs by your software.
Chapter 4 Standby control / MCU control
• STOP mode
[ ] Please note the STPACP is not enabled when both interrupt enable flags and the interrupt request flags are “1” &
MIE flag is “0” (Refer to Section 4.2.2~4.2.3. in the user’s manual).
[ ] Place two NOP instructions next to the instruction that sets the STP bit to “1”(Refer to Section 4.3.3. in the user’s
manual).
• HALT mode
[ ] Place two NOP instructions next to the instruction that sets the HLT bit to “1”(Refer to Section 4.3.2. in the user’s
manual).
• BLKCON registers
[ ] BLKCON registers enable or disable corresponsive each peripheral (Refer to Section 4.2.4 ~ 4.2.8. in the user’s
manual).
[ ] When certain bits of block control registers are set to “1”, corresponding peripherals are reset (all registers are reset)
and operating clocks for the peripherals stop.
[ ] DXTSP bit (bit 4) of BLKCON4 register disables the operation of 32kHz oscillation stop detector in only HALT mode.
Chapter 5 Interrupt
• Unused interrupt vector table
[ ] Please define all unused interrupt vector tables for fail safe.
• Non-maskable interrupt
[ ] The watchdog timer interrupt (WDTINT) and the NMI interrupt (NMINT) are non-maskable interrupts that do not
depend on MIE flag(Refer to Section 5.2.9. and 5.3).
