Functionality

The SR flip-flop, eight channels, nonvolatile function SRGAPC is a simple SR flip-
flop with a memory that can be set or that can reset an output from the S# or R# inputs,
respectively. The function contains eight independent set-reset flip-flop latches where
the SET input has the higher priority over the RESET input. The status of each Q#
output is retained in the nonvolatile memory. The individual reset for each Q# output
is available on the LHMI or through tool via communication.
