Section 26 Pin Function Controller (PFC)
Bits 3, 2—SCP1 Mode 1, 0 (SCP1MD1, SCP1MD0): These bits select the pin functions and the
input pullup MOS control.

Note: There is no combination of simultaneous I/O of SCPT[0] because one bit (SCP0DT) is
accessed using two pins of TxD0 and RxD0.
When the port input is set (bit SCPnMD1 is set to 1) and when the TE bit in SCSCR is set to 1, the
TxD0 pin is in the output state. When the TE bit is cleared to 0, the TxD0 pin is in the high-
impedance state.
