The cursor in the lower left corner of the display indicates that the force set/
reset is in progress. Bit status will remain ON or OFF only as long as the key
is held down; the original status will return one cycle after the key is
released.
3. Press the SHIFT+SET or SHIFT+RESET Keys to maintain the status of the
bit after the key is released. In this case, the force-set status is indicated by
an "S" and the force-reset status is indicated by an "R."
To return the bit to its original status, press the NOT Key or perform the Clear
Force Set/Reset operation. Refer to 4-3-24 Clear Force Set/Reset for
details.
Forced status will also be cleared when the PC's operating mode is changed
(unless SR 25211 is ON, in which case forced status will not be cleared
when changing from PROGRAM to MONITOR mode) or when operation
stops as the result of a fatal error or power interruption.
This operation is used to restore the status of all bits which have been force
set or reset. It is possible in MONITOR or PROGRAM mode only.
