Reset Value:
• PBBDIV: PBB Division Enable
• PBADIV, PBASEL: PBA Division and Clock Select
• CPUDIV, CPUSEL: CPU/HSB Division and Clock Select
Note that if xxxDIV is written to 0, xxxSEL should also be written to 0 to ensure correct operation.
Also note that writing this register clears POSCSR.CKRDY. The register must not be re-written until CKRDY goes high.
