4.8 Interrupt
The EM78P451 has the following interrupts.
1. /TCC overflow interrupt
2. External interrupt (/INT)
3. Serial Peripheral Interface (SPI) transmission completed interrupt.
4. Timer1 comparator completed interrupt.
R3F is the interrupt status register, which records the interrupt request in flag bit. IOCF is the interrupt
mask register. Global interrupt is enabled by ENI instruction and is disabled by DISI instruction. When
one of the interrupts (if enabled) is generated, will cause the next instruction to be fetched from address
001H. Once in the interrupt service routine the source of the interrupt can be determined by polling the
flag bits in the R3F register. The interrupt flag bit must be cleared by software before leaving the
interrupt service routine and enabling interrupts to avoid recursive interrupts.
The flag in the Interrupt Status Register (R3F) is set regardless of the status of its mask bit or the
execution of ENI instruction. Note that reading R3F will obtain the output of logic AND of R3F and IOCF
(refer to Fig. 17). The RETI instruction exits interrupt routine and enables the global interrupt (execution
of ENI instruction).
When an interrupt is generated by INT instruction (if enabled), it causes the next instruction to be
