Note Be sure to clear bits 5 and 7 of IF0L to 0.
Cautions 1. When operating a timer, serial interface, or A/D converter after standby release, operate it

Be sure to clear bits 0 and 5 to 7 of IF0H to 0.
Be sure to clear bits 0 and 1 of IF1L to 0.
Be sure to clear bits 1 and 2 and 5 to 7 of IF1H to 0.
2. When manipulating a flag of the interrupt request flag register, use a 1-bit memory

manipulation instruction (CLR1). When describing in C language, use a bit manipulation
instruction such as “IF0L.0 = 0;” or “_asm(“clr1 IF0L, 0”);” because the compiled
assemblermust be a 1-bit memory manipulation instruction (CLR1).
described in C language using an 8-bit memory manipulation instruction such as “IF0L &=
0xfe;” and compiled, it becomes the assembler of three instructions.
In this case, even if the request flag of another bit of the same interrupt request flag register
(IF0L) is set to 1 at the timing between “mov a, IF0L” and “mov IF0L, a”, the flag is cleared
to 0 at “mov IF0L, a”. Therefore, care must be exercised when using an 8-bit memory
manipulation instruction in C language.
