WATCHDOG (if enabled):
The device comes out of reset with both the WATCHDOG logic and the Clock Monitor
detector armed, with the WATCHDOG service window bits set and the Clock Monitor bit set.
The WATCHDOG and Clock Monitor circuits are inhibited during reset. The WATCHDOG
service window bits being initialized high default to the maximum WATCHDOG service
window of 64k T0 clock cycles. The Clock Monitor bit being initialized high will cause a Clock
Monitor error following reset if the clock has not reached the minimum specified frequency at
the termination of reset. A Clock Monitor error will cause an active low error output on pin
G1. This error output will continue until 16–32 T0 clock cycles following the clock frequency
reaching the minimum specified value, at which time the G1 output will go high.
5.7.1
External Reset
The RESET input when pulled low initializes the device. The RESET pin must be held low for a minimum
of one instruction cycle to ensure a valid reset. During Power-Up initialization, the user must ensure that
the RESET pin of a device without the Brownout Reset feature is held low until the device is within the
specified VCC voltage. Any rising edge on the RESET pin while VCC is below the specified operating range
may cause unpredictable results. An R/C circuit on the RESET pin with a delay 5 times (5x) greater than
the power supply rise time is recommended. Reset should also be wide enough to ensure crystal start-up
upon Power-Up.
RESET may also be used to cause an exit from the HALT mode.
A recommended reset circuit for this device is shown in Figure 5-3.
