13.2.8
The serial port register (SCSPTR) is an 8-bit register that the CPU can always read and write. It
controls I/O and data of the port multiplexed with the serial communications interface (SCI) pins.
Input data can be read from the RxD pin and output data can be transmitted to the TxD pin; this
controls breaks for serial transmission and reception.
SCSPTR is initialized to H'00 by a power-on reset. It is not initialized by a manual reset or in
standby mode.
Bits 7 to 4—Reserved: These bits always read 0. The write value should always be 0.
Bit 3—Serial Port Clock Port I/O (SPB1IO): Specifies serial port SCK pin input/output. When the
SCK pin is actually set as a port output pin and outputs the value set by the SPB1DT bit, the C/A
bit in SCSMR and the CKE1 and CKE0 bits in SCSCR should be cleared to 0.
Bit 3: SPB1IO

1
Bit 2—Serial Port Clock Port Data (SPB1DT): Specifies the serial port SCK pin input/output data.
Input or output is specified by the SPB1IO bit (see the description of SPB1IO for details). When
output is specified, the value of the SPB1DT bit is output to the SCK pin. The SCK pin value is
read from the SPB1DT bit regardless of the value of the SPB1IO bit. The initial value of this bit
after a power-on reset is undefined.
Bit 2: SPB1DT
0
1
Bit 1—Serial Port Break I/O (SPB0IO): Specifies the serial port TxD pin output condition. When
the TxD pin is actually set as a port output pin and outputs the value set by the SPB0DT bit, the
TE bit in SCSCR should be cleared to 0.
