FCOP — Force COP Watchdog Failure
CBYP2 — Timer Counter 2 Chain By-pass
The following table shows the pin usage for the MC68HC11G5.
The following paragraphs describe the input/output signals used by the various functions of
the MCU.

0 – Normal operation
1 – 16-bit free running timer counter 2 is divided into 8-bit halves and the prescaler is
The DISR control bit has priority over the FCM and FCOP control bits such that, if DISR
is set to one, no reset results even when FCM or FCOP is set to one.
