16.2.11 Serial Port Register (SCSPTR2)
SCSPTR2 is a 16-bit readable/writable register that controls input/output and data for the port pins
multiplexed with the serial communication interface with FIFO (SCIF) pins. Input data can be
read from the RxD2 pin, output data written to the TxD2 pin, and breaks in serial
transmission/reception controlled, by means of bits 1 and 0. Data can be read from, and output
data written to, the SCK2 pin by means of bits 3 and 2. Data can be read from, and output data
written to, the CTS2 pin by means of bits 5 and 4. Data can be read from, and output data written
to, the RTS2 pin by means of bits 6 and 7.
SCSPTR2 can be read or written to by the CPU at all times. All SCSPTR2 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. SCSPTR2 is not initialized in standby mode or in the module standby state.
Bits 15 to 8—Reserved: These bits are always read as 0, and should only be written with 0.
Bit 7—Serial Port RTS Port I/O (RTSIO): Specifies the serial port RTS2 pin input/output
condition. When the RTS2 pin is actually set as a port output pin and outputs the value set by the
RTSDT bit, the MCE bit in SCFCR2 should be cleared to 0.
