Pulse I/O Board Section 2-2
Instructions Applicable during Output
Some instructions relating to pulse output cannot be altered once output has
begun. The following table lists those instructions that can and cannot be exe-
cuted to change pulse output after another instruction has been executed (i.e.,
while pulse output is being performed as a result of a former instruction).
Note The number of pulses can be changed, but the direction cannot be changed.
INI(61)
(MODE CONTROL)
Halts pulse output. Yes Yes Yes Yes
PRV(62)
(HIGH-SPEED
