3. Interrupt Control Circuit
Internal/External
Two of the internal interrupt sources are pseudo nonmaskable while the rest are maskable.
The interrupt latch is set to “1” by the generation of its interrupt request which requests the CPU to accept its inter-
rupts. Interrupts are enabled or disabled by software using the interrupt master enable flag (IMF) and interrupt enable
flag (EF). If more than one interrupts are generated simultaneously, interrupts are accepted in order which is domi-
nated by hardware. However, there are no prioritized interrupt factors among non-maskable interrupts.
The TMP88CS43FG has a total of 35 interrupt sources excluding reset. Interrupts can be nested with priorities.
Interrupt sources are provided with interrupt latches (IL), which hold interrupt requests, and independent vectors.
