4-1-3 Hexadecimal/BCD Data Modification
When the Bit/Multibit Monitor operation is being performed and a BCD or
hexadecimal value is leftmost on the display, CHG can be input to change
the value. Dedicated words cannot be changed.
If a timer or counter is leftmost on the display, the PV will be displayed and
will be the value changed. PV can be changed in RUN mode only when the
timer or counter is operating.
To change contents of the leftmost word address, press CHG, input the de-
sired value, and press ENT.
