Port K

The pin function of port K can be switched with that of port E according to the combination of

operating mode, the EXPE bit, and the PCJKE bit settings. The pin function of port K can be

switched according to the PCJKE bit setting in the single-chip mode (EXPE = 0). However, do not

change the setting of the PCJKE bit in external extended mode. For details, see section 13.3.12,

Port Function Control Register D (PFCRD).
