Syntax:
R (RESET)
Operands:
M, I, O, T, C
Action:
If the logic accumulator = 1, then set the addressed operand to 0, otherwise
do not change it. Use the R command at the end of a sequence of logical
gating operations in order to influence an operand independently from the
result of gating. This command can be used several times in succession (see
example).
Example:
Gate input I4 and I5 with OR. If the gating result is 1, then reset output O2 and
marker M500.
Initial state:
Input
I4
= 1
Input
I5
= 0
Output
O2
= ?
Marker
M500 = ?
