SC Port Control Register (SCPCR) is a 16-bit read/write register that selects the pin functions. The
setting of SCPCR is valid only when the transmit/receive operation is disabled in the setting of the
SCSCR register. SCPCR is initialized to H'8008 by power-on resets; however, it is not initialized
by manual resets, in standby mode, or in sleep mode. 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 TxD[2:0] pin. When
the RE bit in SCSCR is set to 1, the input state has a higher priority than the SCPCR setting of the
RxD[2:0] pin.
Bits 15, 14—SCP7 Mode 1, 0 (SCP7MD1, SCP7MD0): These bits select the pin functions and
the input pullup MOS control.
