accurate measurement of the program's size.
This section explains how to write the CPU Unit's data to a Flash-memory or
EEPROM Memory Cassette.
Note A PROM Writer and Support Software are needed to write data to an EPROM
Memory Cassette. Refer to the Support Software's Operation Manual for
details.
Follow the procedure outlined below to write to a Flash-memory or EEPROM
Memory Cassette.
1. Check to see that the write-protect switch on the Memory Cassette is OFF
(i.e., writing enabled). The Memory Cassette Write-protected Flag
(AR 1302) will be OFF if writing is enabled.
If the switch is ON (i.e., writing not enabled), then turn the CQM1H power
supply OFF and remove the Memory Cassette before changing the switch.
2. Check to see that the CQM1H is in PROGRAM mode. If it is in either RUN
or MONITOR mode, use a Programming Device to change the mode.
3. Turn ON AR 1400 from a Programming Device. The information will be
written from the CQM1H to the Memory Cassette. When the operation is
completed, AR 1400 will be turned OFF automatically.
occurred.
Note If an error occurs while data is being transmitted, a non-fatal error (FAL 9D)
will be generated and the appropriate AR bit (from AR 1412 to AR 1415) will
turn ON/OFF. If this occurs, refer to SECTION 8 Troubleshooting and make
the necessary corrections.
There are two ways to read from the Memory Cassette. The Memory Cas-
sette to CPU Unit Transfer Bit (AR 1401) can be turned ON from a Program-
ming Device or pin 2 of the CPU Unit's DIP switch can be turned ON to
automatically read data from the Memory Cassette at startup.
If the program on the Memory Cassette has expansion instructions with func-
tion codes different from the default settings, make sure that pin 4 of the CPU
Unit's DIP switch is ON (indicating user-allocated function codes).
The contents of the Memory Cassette cannot be read from the program.
Reading from the Memory Cassette can be executed regardless of the type of
Memory Cassette.
If an error occurs while data is being transmitted, a non-fatal error (FAL 9D)
will be generated and the appropriate AR bit (from AR 1412 to AR 1415 will
turn ON/OFF. (If this occurs, refer to the Troubleshooting section and make
the necessary correction.)
To use a Programming Device to read from the Memory Cassette, follow the
procedure outlined below.
1. Check to see that the CQM1H is in PROGRAM mode. If it is in either RUN
or MONITOR mode, use the Programming Device to change the mode.
