27.3.12 Serial Port Register (SCSPTR)
SCSPTR is a 16-bit readable/writable register that controls input/output and data for the port pins
multiplexed with the serial communication interface (SCIF) pins at all times. Input data can be
read from the SCIF_RXD pin, output data written to the SCIF_TXD pin, and breaks in serial
transmission/reception controlled, by means of bits 1 and 0.
All SCSPTR bits except bits 6, 4, 2, and 0 are initialized to 0 by a power-on reset or manual reset;
the value of bits 6, 4, 2, and 0 is undefined. SCSPTR is not initialized in the module standby state.
Note that when reading data via a serial port pin in the SCIF, the peripheral clock value from 2
cycles before is read.

Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Serial Port SCIF_RTS Port Input/Output
Specifies the serial port SCIF_RTS pin input/output
condition. When actually setting the SCIF_RTS pin as a
port output pin to output the value set by the RTSDT bit,
the MCE bit in SCFCR should be cleared to 0.
0: RTSDT bit value is not output to SCIF_RTS pin
1: RTSDT bit value is output to SCIF_RTS pin
Serial Port SCIF_RTS Port Data
Specifies the serial port SCIF_RTS pin input/output
data. Input or output is specified by the RTSIO bit. In
output mode, the RTSDT bit value is output to the
SCIF_RTS pin. The SCIF_RTS pin value is read from
the RTSDT bit regardless of the value of the RTSIO bit.
The initial value of this bit after a power-on reset or
manual reset is undefined.
0: Input/output data is low-level
1: Input/output data is high-level
