Caution 3. Use the 1-bit memory manipulation instruction (CLR1) for manipulating the flag of the
interrupt request flag register. A 1-bit manipulation instruction such as “IF0L.0 = 0;” and
“_asm(“clr1 IF0L, 0”);” should be used when describing in C language, because assembly
instructions after compilation must be 1-bit memory manipulation instructions (CLR1).
If an 8-bit memory manipulation instruction “IF0L & = 0xfe;” is described in C language, for
example, it is converted to the following three assembly instructions after compilation:
In this case, at the timing between “mov a, IF0L” and “mov IF0L, a”, if the request flag of
another bit of the identical interrupt request flag register (IF0L) is set to 1, it is cleared to 0
by “mov IF0L, a”. Therefore, care must be exercised when using an 8-bit memory
manipulation instruction in C language.
