CHAPTER 3: PERIPHERAL CIRCUITS (Interrupt and Halt)
The S1C6S2N7 supports four types of a total of 10
interrupts. There are one motor driver interrupt, three timer
interrupts (2 Hz, 8 Hz, 32 Hz), two stopwatch interrupts (1
Hz, 10 Hz) and four input interrupts (K00–K03).
The 10 interrupts are individually enabled or masked (dis-
abled) by interrupt mask registers. The EI and DI instruc-
tions can be used to set or reset the interrupt flag (I), which
enables or disables all the interrupts at the same time.
When an interrupt is accepted, the interrupt flag (I) is reset,
and cannot accepts any other interrupts (DI state).
Restart from the halt state created by the HALT instruction,
is done by interrupt.
