Changing the SRCLK bits while the SR latch is enabled may cause false triggers to the set and Reset
inputs of the latch.
SRLEN: SR Latch Enable bit
1 = SR latch is enabled
0 = SR latch is disabled
SRCLK<2:0>
000 = 1/4 Peripheral cycle clock
001 = 1/8 Peripheral cycle clock
010 = 1/16 Peripheral cycle clock
011 = 1/32 Peripheral cycle clock
100 = 1/64 Peripheral cycle clock
101 = 1/128 Peripheral cycle clock
110 = 1/256 Peripheral cycle clock
111 = 1/512 Peripheral cycle clock
SRQEN: SR Latch Q Output Enable bit
1 = Q is present on the RA2 pin
0 = Q is internal only
SRNQEN: SR Latch Q Output Enable bit
1 = Q is present on the RC4 pin
0 = Q is internal only
SRPS: Pulse Set Input of the SR Latch bit
1 = Pulse input
0 = Always reads back ‘0’
SRPR: Pulse Reset Input of the SR Latch bit
1 = Pulse input
0 = Always reads back ‘0’
