5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Interrupt and Standby Status)
5.14.2 Interrupt factor flag
Table 5.14.2.1 shows the correspondence between
the factors generating an interrupt and the inter-
rupt factor flags.
The corresponding interrupt factor flags are set to
"1" by generation of the respective interrupt factors.
The corresponding interrupt factor can be con-
firmed by reading the flags through software.
Interrupt factor flag that has been set to "1" is reset
to "0" by writing "1".
At initial reset, the interrupt factor flags are reset to "0".
Note: When executing the RETE instruction
without resetting the interrupt factor flag after
an interrupt has been generated, the same
interrupt will be generated. Consequently,
the interrupt factor flag corresponding to that
routine must be reset (writing "1") in the
interrupt processing routine.
