Note 1: IL3 is a read-only register. Writing the register does not affect interrupt latch.
Note 2: In the main program, before manipulating an interrupt latch (IL), be sure to clear the interrupt master enable flag (IMF) to
Note 3: Do not clear IL with read-modify-write instructions such as bit operations.
Note 4: When a read instruction is executed on ILL, bits 0 to 2 are read as "0". Other unused bits are read as "0".

"0" (Disable interrupt by DI instruction). Then set the IMF to "1" as required after operating the IL (Enable interrupt by EI
instruction).
In the interrupt service routine, the IMF becomes "0" automatically and need not be cleared to "0" normally. However, if
using multiple interrupt in the interrupt service routine, manipulate the IL before setting the IMF to "1".
