NOTE:
Address:
PBPU0/COPC programmed to a 1 enables the port B pullup bit. This bit
is also used to clear the non-programmable COP (MC68HC05C4A
type). Writing to this bit to clear the COP will not affect the state of the
port B pull-up (bit 0). See
Non-Programmable COP Watchdog
When using the MC68HC705C8A in an MC68HC705C8 or
MC68HSC705C8 application, program locations $1FF0 and $1FF1 to
$00.
Mask option register 2 (MOR2) shown in
register that enables the non-programmable COP watchdog. Data from
MOR2 is latched on the rising edge of the voltage on the RESET pin.
