16.3.11 Serial Port Register (SCSPTR)
SCSPTR controls input/output and data of pins multiplexed to SCIF function. Bits 3 and 2 can
control input/output data of SCK pin. Bits 1 and 0 can input data from RxD pin and output data to
TxD pin, so they control break of serial transmitting/receiving.
The CPU can always read and write to SCSPTR. SCSPTR is initialized to H'0050 by a power-on
reset or in deep standby mode.

Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Reserved
This bit is always read as 1. The write value should
always be 1.

Reserved
This bit is always read as 1. The write value should
always be 1.
SCK Port Input/Output
Indicates input or output of the serial port SCK pin.
When the SCK pin is actually used as a port outputting
the SCKDT bit value, the CKE[1:0] bits in SCSCR
should be cleared to 0.
0: SCKDT bit value not output to SCK pin
1: SCKDT bit value output to SCK pin
