tered, the PC will shift to the mode set on the mode switch, causing PC op-
eration to begin if the mode is set to RUN or MONITOR. The mode can be
changed to RUN or MONITOR with the mode switch after entering the pass-
word.
Indicates the mode set by the mode selector switch.
Immediately after the password is input or anytime immediately after the
mode has been changed, SHIFT and then the 1 key can be pressed to turn
on and off the beeper that sounds when Programming Console keys are
pressed. If BZ is displayed in the upper right corner, the beeper is operative.
If BZ is not displayed, the beeper is not operative.
This beeper also will also sound whenever an error occurs during PC opera-
tion. Beeper operation for errors is not affected by the above setting.
Using the Memory Clear operation it is possible to clear all or part of the Pro-
gram Memory, and the IR, HR, AR, DM and TC areas. Unless otherwise
specified, the clear operation will clear all of the above memory areas, pro-
vided that the Memory Unit attached to the PC is a RAM Unit or an EEPROM
Unit and the write-enable switch is ON. If the write-enable switch is OFF or
the Memory Unit is an EPROM Unit, Program Memory cannot be cleared.
Before beginning to programming for the first time or when installing a new
program, all areas should normally be cleared. Before clearing memory,
check to see if a program is already loaded that you need. If you need the
program, clear only the memory areas that you do not need, and be sure to
check the existing program with the program check key sequence before us-
ing it. The check sequence is provided later in this section. Further debug-
ging methods are provided in Section 7 Program Debugging and Execution.
To clear all memory areas press CLR until all zeros are displayed, and then
input the keystrokes given in the top line of the following key sequence. The
branch lines shown in the sequence are used only when performing a partial
memory clear, which is described below.
Memory can be cleared in PROGRAM mode only.
