Section 26 Pin Function Controller (PFC)
Bits 11, 10—SCP5 Mode 1, 0 (SCP5MD1, SCP5MD0): These bits select the pin functions and
the input pullup MOS control.

Note: There is no combination of simultaneous I/O of SCPT[4] because one bit (SCP4DT) is
accessed using two pins of TxD2 and RxD2.
When the port input is set (bit SCPnMD1 is set to 1) and when the TE bit in SCSCR is set to 1, the
TxD2 pin is in the output state. When the TE bit is cleared to 0, the TxD2 pin is in the high-
impedance state.
