3. Interrupt Control Circuit
Internal/External
Four of the internal interrupt sources are non-maskable 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 interrupts.
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 dominated
by hardware. However, there are no prioritized interrupt factors among non-maskable interrupts.
The TMP86FH92DMG has a total of 22 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.
