5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Stopwatch Timer)
5.9.3 Interrupt function
The stopwatch timer can generate an interrupt by
each of the 100 Hz (approximately 100 Hz), 10 Hz
(approximately 10 Hz) and 1 Hz signals.
Figure 5.9.3.1 shows the configuration of the
stopwatch timer interrupt circuit
The corresponding factor flags FSW100, FSW10 and
FSW1 are respectively set to "1" at the falling edge
of the 100 Hz, 10Hz and 1Hz signal and an inter-
rupt is generated. Interrupt can be prohibited by
the setting of the interrupt enable registers ESW100,
ESW10 and ESW1 corresponding to each interrupt
factor flag.
In addition, a priority level of the stopwatch timer
interrupt for the CPU can be optionally set at levels
0 to 3 by the interrupt priority registers PSW0 and
PSW1.
For details on the above mentioned interrupt
control registers and the operation following
generation of an interrupt, see "5.14 Interrupt and
Standby Status".
The exception processing vector addresses of each
interrupt factor are respectively set as shown
below.

1 Hz interrupt:
