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.
