MC68HC912BD32 Rev 1.0
There is a real-time (periodic) interrupt available to the user. This
interrupt will occur at one of seven selected rates. An interrupt flag and
an interrupt enable bit are associated with this function. There are three
bits for the rate select.
The clock monitor circuit is based on an internal resistor-capacitor (RC)
time delay. If no MCU clock edges are detected within this RC time
delay, the clock monitor can optionally generate a system reset. The
clock monitor function is enabled/disabled by the CME control bit in the
COPCTL register. This time-out is based on an RC delay so that the
clock monitor can operate without any MCU clocks.
Clock monitor time-outs are shown in
