• CPUDIV, CPUSEL: CPU Division and Clock Select
Note that if CPUDIV is written to 0, CPUSEL 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.
Note that this register is protected by a lock. To write to this register the UNLOCK register has to be written first. Please ref-
ere to the UNLOCK register description for details.
