S12 Clock, Reset and Power Management Unit (S12CPMU)
10.3.2.6
This register controls S12CPMU clock selection.
Read: Anytime
Write:

0x0039
Reset
1. Only possible if PROT=0 (CPMUPROT register) in all MCU Modes (Normal and Special Mode).
2. All bits in Special Mode (if PROT=0).
3. PLLSEL, PSTP, PRE, PCE, RTIOSCSEL: In Normal Mode (if PROT=0).
4. COPOSCSEL0: In Normal Mode (if PROT=0) until CPMUCOP write once has taken place.
5. COPOSCSEL1: In Normal Mode (if PROT=0) until CPMUCOP write once is taken.

PLLSEL
If COPOSCSEL0 was cleared by UPOSC=0 (entering Full Stop Mode with COPOSCSEL0=1
or insufficient OSCCLK quality), then COPOSCSEL0 can be set once again.
COPOSCSEL1 will not be cleared by UPOSC=0 (entering Full Stop Mode with
COPOSCSEL1=1 or insufficient OSCCLK quality if OSCCLK is used as clock source for
other clock domains: for instance core clock etc.).
S12CPMU Clock Select Register (CPMUCLKS)

After writing CPMUCLKS register, it is strongly recommended to read
back CPMUCLKS register to make sure that write of PLLSEL,
RTIOSCSEL, COPOSCSEL0 and COPOSCSEL1 was successful.
