Note:

In single-chip mode, the port D and port E functions can be used in the initial state.

Pin functions are selectable by setting the PCJKE bit in PFCRD.

Ports D and E are enabled when PCJKE=0 (initial value) and ports J and K are enabled

when PCJKE=1.

In external extended mode, only ports D and E can be used.

Supported only by the H8SX/1668MGroup.
