Bits 11 and 10—SCP5 Mode 1 and 0 (SCP5MD1, SCP5MD0): These bits select the pin
functions and perform input pull-up MOS control.

General input (SCPT[4] input pin)
Transmit data output 2 (TxD2)
Note:
There is no SCPT[4] simultaneous I/O combination because one bit (SCP4DT) is accessed
using two pins, TxD2 and RxD2.
When 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 goes to the high-
impedance state.
Bits 7 and 6—SCP3 Mode 1 and 0 (SCP3MD1, SCP3MD0): These bits select the pin function
and perform input pull-up MOS control.
