Bit Bit Name
Initial
Value R/W Description
14 SLNDEN 0 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.
13 SPNDEN 0 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.
