4.3.3.1 Power-On Reset
Technical Data
72
A power-on reset (POR) is an internal reset caused by a positive
transition on the V
reset the MCU. This distinguishes between a reset and a POR. The POR
is not a brown-out detector, low-voltage detector, or glitch detector.
A power-on reset:

RESET
OSC1
Holds the clocks to the CPU and modules inactive for an oscillator
stabilization delay of 4096 CGMXCLK cycles
Drives the RST pin low during the oscillator stabilization delay
Releases the RST pin 32 CGMXCLK cycles after the oscillator
stabilization delay
Releases the CPU to begin the reset vector sequence 64
CGMXCLK cycles after the oscillator stabilization delay
Sets the POR and LP bits in the SIM reset status register and
clears all other bits in the register
