4-3-5 Setting and Reading a Program Memory Address and Monitoring I/O Bit Status

This operation is used to display the specified program memory address and is possible in any mode. In the RUN or MONITOR mode, the I/O bit status of bits in the program will be displayed.

RUN	MONITOR	PROGRAM
OK	OK	OK

When inputting a program for the first time, it is generally written to Program Memory starting from address 000. Because this address appears when the display is cleared, it is not necessary to specify it.

When inputting a program starting from other than 000 or to read or modify a program that already exists in memory, the desired address must be desig- nated.

1, 2, 3... 1. Press the CLR Key to bring up the initial display.

2. Input the desired address. It is not necessary to input leading zeroes.

C	A	A	00200
2	0		0

3. Press the Down Arrow Key.

↓	00200READ	OFF
	LD	00000

In the RUN or MONITOR mode, ON/

OFF status of the bit will be displayed.

Note The ON/OFF status of any displayed bit will be shown if the PC is in

RUN or MONITOR mode.

4. Press the Up and Down Arrow Keys to scroll through the program.

↓	00201READ	ON
	AND	00001
↑	00200READ	OFF
	LD	00000

Pressing the MONTR Key will change to the I/O monitor display. Bits can be force-set or force-reset from the I/O monitor display. Press the CLR Key to return to I/O bit status monitoring of the initial address.
