Read anytime, write anytime, except when BCSP = 1 (PLL selected as
bus clock).
If the PLL is on, the count in the loop divider (SYNR) register effectively
multiplies up the bus frequency from the PLL reference frequency by
SYNR + 1. Internally, SYSCLK runs at twice the bus frequency. Caution
should be used not to exceed the maximum rated operating frequency
for the CPU.
Read anytime, write anytime, except when BCSP = 1.
The reference divider bits provides a finer granularity for the PLL
multiplier steps. The reference frequency is divided by REFDV + 1.
Always reads zero, except in test modes.
