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.

PBBDIV = 0: PBB clock equals main clock.
PBBDIV = 1: PBB clock equals main clock divided by 2
PBADIV = 0: PBA clock equals main clock.
PBADIV = 1: PBA clock equals main clock divided by 2
For the AT32UC3A, HSBDIV always equals CPUDIV, and HSBSEL always equals CPUSEL, as the HSB clock is always equal to
the CPU clock.
CPUDIV = 0: CPU clock equals main clock.
CPUDIV = 1: CPU clock equals main clock divided by 2
