Hardware of Interrupt Control Circuit
This section describes the flags of the interrupt control circuit.
(1)
Interrupt request flag and interrupt enable flag
The interrupt request flag (IRQxxx) is set to 1 when an interrupt request is generated, and is automatically
cleared to 0 when the interrupt processing is excuted.
An interrupt enable flag (IPxxx) is provided to each interrupt request flag. When the IPxxx flag is 1, the interrupt
is enabled; when it is 0, the interrupt is disabled.
EI/DI instruction
Whether an accepted interrupt is executed or not is specified by the EI or DI instruction.
When the EI instruction is executed, INTE (interrupt enable flag), which enables the interrupt, is set to 1. The
INTE flag is not registered on the register file. Consequently, the status of this flag cannot be checked by an
instruction.
The DI flag clears the INTE flag to 0 to disable all the interrupts.
The INTE flag is also cleared to 0 at reset, disabling all the interrupts.
