5.4 RESET Pin
The MCU is reset when a logic 0 is applied to the RESET input for a
period of one and one-half machine cycles (t
cyc).
5.5 Computer Operating Properly (COP) Reset
The MCU contains a watchdog timer that automatically times out if not
reset (cleared) within a specific time by a program reset sequence. If the
COP watchdog timer is allowed to time out, an internal reset is
generated to reset the MCU. Because the internal RESET signal is
used, the MCU comes out of a COP reset in the same operating mode
it was in when the COP timeout was generated.
The COP reset function is enabled or disabled by a mask option.
