Description
Serial Data Output Value Select
The serial data output retains its level of the last bit
after completion of transmission. The output level
before or after transmission can be specified by setting
this bit. When specifying the output level, use the MOV
instruction after clearing the SOLP bit to 0. Since
writing to this bit during data transmission causes
malfunctions, this bit should not be changed.
0: Serial data output is changed to low.
1: Serial data output is changed to high.
SOL Bit Write Protect
When changing the output level of serial data, set the
SOL bit to 1 or clear the SOL bit to 0 after clearing the
SOLP bit to 0 using the MOV instruction.
0: Output level can be changed by the SOL bit
1: Output level cannot be changed by the SOL bit. This
SSCK Pin Select
Selects that the SSCK pin functions as a port or a serial
clock pin. When the SSCK pin is used as a serial clock
pin, this bit must be set to 1.
0: Functions as an I/O port.
1: Functions as a serial clock.
SCS Pin Select
Select that the SCS pin functions as a port or SCS
input or output. However, when MSS = 0, the SCS pin
functions as an input pin regardless of the CSS1 and
CSS0 settings.
00: I/O port
01: Functions as SCS input
