Changing the SRCLK bits while the SR latch is enabled may cause false triggers to the set and Reset
inputs of the latch.
Set only, always reads back ‘0’.
SRLEN: SR Latch Enable bit
1 = SR latch is enabled
0 = SR latch is disabled
SRCLK<2:0>: SR Latch Clock Divider Bits
000 = Generates a 2 T
001 = Generates a 2 T
010 = Generates a 2 T
011 = Generates a 2 T
100 = Generates a 2 T
101 = Generates a 2 T
110 = Generates a 2 T
111 = Generates a 2 T
SRQEN: SR Latch Q Output Enable bit
1 = Q is present on the SRQ pin
0 = Q is internal only
SRNQEN: SR Latch Q Output Enable bit
1 = Q is present on the SRNQ pin
0 = Q is internal only
SRPS: Pulse Set Input of the SR Latch bit
1 = Pulse set input for 2 T
0 = No effect on set input
SRPR: Pulse Reset Input of the SR Latch bit
1 = Pulse reset input for 2 T
0 = No effect on Reset input
