21.3.12 Serial
Port
Register n (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.

Port Input/Output
Specifies the serial port

pin input/output
condition. When actually setting the
SCIF0_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
