7 SSLKP 0 R/W SSL Signal Level Keeping
When this module in master mode performs a serial
transfer, this bit specifies whether the SSL signal
level for the current command is to be kept or
negated between the SSL negation timing
associated with the current command and the SSL
assertion timing associated with the next command.
To use this module in slave mode, the SSLKP bit
should be set to 0.
0: Negates all SSL signals upon completion of
transfer.
1: Keeps the SSL signal level from the end of the
transfer until the beginning of the next access.
