CGMRCLK
In user mode, the internal bus frequency is either the oscillator output
(CGMXCLK) divided by four, CGMXCLK divided by two, or the PLL
output (CGMPCLK) divided by four.
When the power-on reset module or the low-voltage inhibit module
generates a reset, the clocks to the CPU and peripherals are inactive
and held in an inactive phase until after the 4096 ICLK cycle POR
timeout has completed. The RST pin is driven low by the SIM during this
entire period. The IBUS clocks start upon completion of the timeout.
