2. When operating a timer, serial interface, or A/D converter after standby release, operate it
3. When manipulating a flag of the interrupt request flag register, use a 1-bit memory
once after clearing the interrupt request flag. An interrupt request flag may be set by noise.
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 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.
