• SOL bit (serial data output level setting)
Although the value in the last bit of transmit data is retained in the serial data output after the
end of transmission, the output level of serial data can be changed by manipulating this bit
before or after transmission.
• SOLP bit (SOL write protect)
When output level of serial data is changed, the MOV instruction is used to set the SOL bit to
1 and clear this bit to 0 or to clear the SOL bit and this bit to 0.
• SRES bit (software reset)
When this bit is set to 1, the SSU internal sequencer is forcibly reset. The register value in the
SSU is retained.
