TMP86FS49BUG
3. Interrupt Control Circuit
The TMP86FS49BUG has a total of 24 interrupt sources excluding reset. Interrupts can be nested with priorities.
Four of the internal interrupt sources are non-maskable while the rest are maskable.
Interrupt sources are provided with interrupt latches (IL), which hold interrupt requests, and independent vectors.
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.
Note 1: To use the address trap interrupt (INTATRAP), clear WDTCR1<ATOUT> to “0” (It is set for the “reset request” after reset is
cancelled). For details, see “Address Trap”.
Note 2: To use the watchdog timer interrupt (INTWDT), clear WDTCR1<WDTOUT> to "0" (It is set for the "Reset request" after
reset is released). For details, see "Watchdog Timer".
Note 3: If an INTADC interrupt request is generated while an interrupt with priority lower than the interrupt latch IL15 (INTADC) is
being accepted, the INTADC interrupt latch may be cleared without the INTADC interrupt being processed. For details,
refer to the corresponding notes in the chapter on the AD converter.
3.1 Interrupt latches (IL23 to IL2)
An interrupt latch is provided for each interrupt source, except for a software interrupt and an executed the unde-
fined instruction interrupt. When interrupt request is generated, the latch is set to “1”, and the CPU is requested to
accept the interrupt if its interrupt is enabled. The interrupt latch is cleared to "0" immediately after accepting inter-
rupt. All interrupt latches are initialized to “0” during reset.
