SECTION 1. FUNCTIONAL MODES
1-12
PC208W automatically makes use of the
D
Mode to upload and download programs from a
computer. Appendix C gives some additional
information on Commands 1 and 2 that are used
for these operations.
When "
∗
D" is keyed in, the CR23X will display
"13: Enter Command". A command (Table 1.8-
1) is entered by keying the command number
and "A".

If the CR23X program has not been compiled
when the command to save a program is entered,
it will be compiled before the program is saved.
When a program is loaded, it is immediately
compiled and run. When a command is complete,
"13:0000" is displayed;
D
must be entered
again before another command can be given.
If a program download is aborted, the CR23X will
reload the program in its flash into RAM, compile it,
and run it.

1.8.1 INTERNAL FLASH PROGRAM STORAGE
Several programs can be stored in the CR23X
Flash Memory and later recalled and run using
the
D
Mode. The Flash Electrically
Erasable Programmable Read Only Memory is
non-volatile memory that can only be erased in
16K blocks. The CR23X has 512K of Flash
EEPROM memory, one 16K block is reserved
for storing extra programs.
When a program is loaded and compiled, it is
saved as the active program. The active
program will be automatically loaded and run
when the CR23X is powered up. Automatic
loading of the program can be aborted by
pressing any key while “Hello” is showing on the
CR23X display; the display will show “Program
Aborted.” (If a Storage Module with a program
8 is connected when the CR23X powers-up, the
Storage Module program 8 will be loaded into
the CR23X and become the active program.)
The active program can be stored in internal
flash memory program storage with
D
command 6 (Table 1.8-3). Programs can be
retrieved with
D
command 7 (Table 1.8-4).
