3. Interrupt Control Circuit
of the internal interrupt sources are non-maskable while the rest are maskable.
addresses. When a request for an interrupt is generated, its interrupt latch is set to "1", which requests the CPU to
accept the interrupt. Acceptance of interrupts is enabled or disabled by software using the interrupt master enable flag
(IMF) and individual enable flag (EF) for each interrupt source. If multiple maskable interrupts are generated simul-
taneously, the interrupts are accepted in order of descending priority. The priorities are determined by the interrupt
priority change control register (ILPRS1-ILPRS6) as Levels and determined by the hardware as the basic priorities.
Internal/Ex-
The TMP89FM43L has a total of 25 interrupt sources excluding reset. Interrupts can be nested with priorities. Three
Interrupt sources are provided with interrupt latches (IL), which hold interrupt requests, and have independent vector
However, there are no prioritized interrupt sources among non-maskable interrupts.
