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

When this bit is set to 1, the clock synchronous serial
I/O w ith chip select control part 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.
The SOLP bit remains unchanged even if 1 is w ritten to
it. When read, its content is 1.
When read,
0 : The last bit of the serial data output is set to “L”
1 : The last bit of the serial data output is set to “H”
When w rite,
0 : The data outputs “L” after the serial data output
1 : The data outputs “H” after the serial data output
