5 INTERRUPT

5-4

Seiko Epson Corporation

S1C31D50/D51 TECHNICAL MANUAL

(Rev. 2.00)

For specific information on causes of interrupts, interrupt flags, and interrupt enable bits, refer to the respective pe-
ripheral circuit descriptions.

Note: To prevent occurrence of unnecessary interrupts, the corresponding interrupt flag should be

cleared before setting the interrupt enable bit to 1 (interrupt enabled) and before terminating the

interrupt handler routine.

5.4 NMI

The watchdog timer embedded in this IC can generate a non-maskable interrupt (NMI). This interrupt takes prece-
dence over other interrupts and is unconditionally accepted by the CPU.
For detailed information on generating NMI, refer to the “Watchdog Timer” chapter.
