S12 Clock, Reset and Power Management Unit (S12CPMU)
7.3.2
This section describes all the S12CPMU registers and their individual bits.
Address order is as listed in
7.3.2.1
The CPMUSYNR register controls the multiplication factor of the PLL and selects the VCO frequency
range.
Read: Anytime
Write: If PROT=0 (CPMUPROT register) and PLLSEL=1 (CPMUCLKS register), then write anytime.
Else write has no effect.
The VCOFRQ[1:0] bits are used to configure the VCO gain for optimal stability and lock time. For correct
PLL operation the VCOFRQ[1:0] bits have to be selected according to the actual target VCOCLK
frequency as shown in
PLL (no locking and/or insufficient stability).
