Section 26 Pin Function Controller (PFC)
Bits 7, 6—SCP3 Mode 1, 0 (SCP3MD1, SCP3MD0): These bits select the pin functions and the
input pullup MOS control.

Transmit data output 1 (TxD_SIO)
Note: There is no combination of simultaneous I/O of SCPT[2] because one bit (SCP2DT) is
accessed using two pins of TxD_SIO and RxD_SIO.
When the port input is set (bit SCPnMD1 is set to 1) and when the TE bit in SCSCR is set to 1, the
TxD_SIO pin is in the output state. When the TE bit is cleared to 0, the TxD_SIO pin is in the
high-impedance state.
