17.1.10 SC Port Control Register (SCPCR)
SC Port Control Register (SCPCR) is a 16-bit read/write register that selects the pin functions and
the input pull-up MOS control. The setting of SCPCR is valid only when the transmit/receive
operation is disabled in the setting of the SCSCR register. When the TE bit in SCSCR is set to 1,
the other function output state has a higher priority than the SCPCR setting of the TxD2 or TxD0
pin. When the RE bit in SCSCR is set to 1, the input state has a higher priority than the SCPCR
setting of the RxD2 or RxD0 pin.
