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 SCPCR setting is ignored and the TxD function is
selected.
When the RE bit in SCSCR is set to 1, the SCPCR setting is ignored and the RxD function is
selected.
When the TE bit in SCSCR2 is set to 1, the SCPCR setting is ignored and the TxD2 function is
selected.
When the RE bit in SCSCR2 is set to 1, the SCPCR setting is ignored and the RxD2 function is
selected.
