Note 1: To clear any one of bits IL7 to IL4, be sure to write "1" into IL2 and IL3.
Note 2: In main program, before manipulating the interrupt enable flag (EF) or the interrupt latch (IL), be sure to clear IMF to "0"
Note 3: Do not clear IL with read-modify-write instructions such as bit operations.
Note 1: *: Don’t care
Note 2: Do not set IMF and the interrupt enable flag (EF15 to EF4) to “1” at the same time.
Note 3: In main program, before manipulating the interrupt enable flag (EF) or the interrupt latch (IL), be sure to clear IMF to "0"
(Disable interrupt by DI instruction). Then set IMF newly again as required after operating on the EF or IL (Enable interrupt
by EI instruction)
In interrupt service routine, because the IMF becomes "0" automatically, clearing IMF need not execute normally on inter-
rupt service routine. However, if using multiple interrupt on interrupt service routine, manipulating EF or IL should be exe-
cuted before setting IMF="1".
