Cautions 1. Be sure to clear bit 0 of the IF0H register, bits 4 and 5 of the IF1H register (in case of
Figure 18-2. Format of Interrupt Request Flag Registers (IF0L, IF0H, IF1L, IF1H, IF2L) (2/2)
2. When operating a timer, serial interface, or A/D converter after standby release, operate it once
3. When manipulating a flag of the interrupt request flag register, use a 1-bit memory manipulation
78K0R/KC3-L (40-pin), bits 1, 2, 4, and 5), and bits 5 to 7 of the IF2L register (in case of
78K0R/KC3-L (40-pin), bits 4 to 7) to 0.
after clearing the interrupt request flag. An interrupt request flag may be set by noise.
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 assembler must be a 1-bit memory
manipulation instruction (CLR1).
If a program is 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.
