z Set and Reset with Input Downward Differentiation Specification
When the master control is reset, the execution condition changes to FALSE. If the previous execu-
tion condition was TRUE, then the input downward differentiation condition is met. However, during
the master control reset, the previous output value is retained, so as a result the value of the output
is retained.
