SCKBn pin
When CSIBn operation is disabled (CBnCTL0.CBnPWR bit = 0), the SCKBn
pin output status is as follows.
The output level of the SCKBn pin changes if any of the CBnCTL1.CBnCKP
and CBnCKS2 to CBnCKS0 bits is rewritten.
SOBn pin
When CSIBn operation is disabled (CBnPWR bit = 0), the SOBn pin output
status is as follows.
