Operation
The output (Q1) is 1 if the set input (S) is 1 and the reset input (R1) is 0. The output will
retain the previous output state if the set input (S) and the reset input (R1) are 0. The
output is 0 if the reset input is 1.

Operation
The output (Q) is set to 1 when the clock input (CLK) changes from 0 to 1. The output is
set back to 0 with the next execution of the block. Otherwise the output is 0.
Note:
The output (Q) is 1 after the first execution of the block after cold restart when the
clock input (CLK) is 1. Otherwise the output is always 0 when the clock input is 1.
