9.3.2.2
The REFDV register provides a finer granularity for the PLL multiplier steps. The count in the reference
divider divides OSCCLK frequency by REFDV + 1.
Read: anytime
Write: anytime except when PLLSEL = 1
9.3.2.3
This register is reserved for factory testing of the CRGV4 module and is not available in normal modes.
Read: always reads 0x0000 in normal modes
Write: unimplemented in normal modes
