Bit
Bit Name Initial Value R/W Description
1
SCP0MD1 0
R/W SCP0 Mode
0
SCP0MD0 0
R/W 00: Transmit data output 0 (TxD0)
Receive data input 0 (RxD0)
01: General output (SCPT[0] output pin)
Receive data input 0 (RxD0)
10: SCPT[0] input pin pull-up (input pin)
Transmit data output 0 (TxD0)
11: General input (SCPT[0] input pin)
Transmit data output 0 (TxD0)
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.
