Chapter 11 S12XE Clocks and Reset Generator (S12XECRGV1)
11.3.2.2
The REFDV register provides a finer granularity for the IPLL multiplier steps.
Read: Anytime
Write: Anytime except when PLLSEL = 1
The REFFRQ[1:0] bit are used to configure the internal PLL filter for optimal stability and lock time. For
correct IPLL operation the REFFRQ[1:0] bits have to be selected according to the actual REFCLK
frequency as shown in
IPLL (no locking and/or insufficient stability).
11.3.2.3
The POSTDIV register controls the frequency ratio between the VCOCLK and PLLCLK. The count in the
final divider divides VCOCLK frequency by 1 or 2*POSTDIV. Note that if POSTDIV = $00 f
(divide by one).
