Notes: 1. Pin names SCK, RxD, TxD,

CTS, and RTS are used in this manual for all channels,

omitting the channel designation.

2. These pins are used as serial pins by setting the SCIF with the TE and RE bits in SCIF

and the MCE bit in SCFCR.

3. The SCK pin can be set as input (input enabled or disabled).
