Section 5. Resets
5.1 Contents
5.2 Introduction
The MCU can be reset three ways:
1. Initial power-on reset function
2. Active low input to the RESET pin
3. Computer operating properly (COP) watchdog timer timeout
5.3 Power-On Reset (POR)
An internal reset is generated on power-up to allow the internal clock
generator to stabilize. The power-on reset is strictly for power turn-on
conditions and should not be used to detect a drop in the power supply
voltage.
There is a 4064 internal processor clock cycle (tcyc) oscillator
stabilization delay after the oscillator becomes active. If the RESET pin
is low at the end of this 4064-cycle delay, the MCU will remain in the
reset condition until RESET goes high.
