SLNDEN 
R/W 
SSL Negation Delay Setting Enable 
Sets the period from the point this module in master 
mode stops RSPCK oscillation until this module sets 
the SSL signal inactive (SSL negation delay). If the 
SLNDEN bit is 0, this module sets the SSL negation 
delay to 1 RSPCK. If the SLNDEN bit is 1, this 
module negates the SSL signal at an SSL negation 
delay in compliance with the slave select negation 
delay register (SSLND) settings. 
To use this module in slave mode, the SLNDEN bit 
should be set to 0. 
0: An SSL negation delay of 1 RSPCK 
1: An SSL negation delay equal to SSLND settings.

SPNDEN 
R/W 
Next-Access Delay Enable 
Sets the period from the point this module in master 
mode terminates a serial transfer and sets the SSL 
signal inactive until this module enables the SSL 
signal assertion for the next access (next-access 
delay). If the SPNDEN bit is 0, this module sets the 
next-access delay to 1 RSPCK + 2B
. If the 
SPNDEN bit is 1, this module inserts a next-access 
delay in compliance with the next-access delay 
register (SPND) settings. 
To use this module in slave mode, the SPNDEN bit 
should be set to 0. 
0: A next-access delay of 1 RSPCK 
 2 B 
1: A next-access delay equal to SPND settings.
