Interrupt Control Circuit

Interrupt enable register (EIR)
TMP86FH46BNG
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 in-
terrupt service routine. However, if using multiple interrupt on interrupt service routine, manipulating EF or IL should
be executed before setting IMF="1".
