Registers SSCRH, SSCRL, SSMR, SSER, SSSR, SSMR2, SSTDR, and SSRDR.
The data output after serial data is output can be changed by w riting to the SOL bit before or after transfer. When
w riting to the SOL bit, set the SOLP bit to 0 and the SOL bit to 0 or 1 simultaneously by the MOV instruction.
Do not w rite to the SOL bit during data transfer.

When this bit is set to 1, the clock synchronous serial
I/O w ith chip select control block and SSTRSR register
are reset.
The values of the registers
serial I/O w ith chip select register are maintained.
The output level can be changed by the SOL bit w hen
this bit is set to 0.
Cannot w rite to this bit. When read, the content is 1.
When read
0 : The serial data output is set to “L”.
1 : The serial data output is set to “H”.
When w ritten,
0 : The data output is “L” after the serial data output.
1 : The data output is “H” after the serial data output.
