pin input, or the overflow at the timer. These
events set flags IFA, IFB and IFT respectively, that
then serve as interrupt request flag.
Table 4 shows interrupt handling priority level and
jump address.

Usage of halt mode and stop mode
The system returns back to the normal operation
mode upon occurring of a standby mode releasing
condition. The halt mode should be used when the
system must enter and exit normal operation
frequently as in the case of key operation.
The halt mode should also be used to keep timers
that are operating from the internal clock, while in
the standby mode.
The stop mode further saves power than the halt
mode but requires slightly longer time to return to
the normal mode. Therefore, the stop mode should
be used when the system will not be required to
return to the normal mode in a short time.
Interrupt Feature
The interrupt block consists of mask flags (bits RE0,
RE1 and RE2), IME flag and interrupt request
handling circuit. Fig. 9 shows the configuration of the
interrupt block.
