Chapter 6. Ipl (Initial Program Loading) Function - Sharp XE-A202 Service Manual

CHAPTER 6. IPL (INITIAL PROGRAM LOADING) FUNCTION

The application program of the XE-A202 is written into the Flash ROM
in the CPU.
Since the CPU supplied as a service part does not include the applica-
tion program in it, the application program must be written when the
CPU is replaced with a new one.
To write the application program into the Flash ROM, connect the PC
and the XE-A202 with an RS-232C cable, and execute the PC software.
*Use a D-Sub 9pin cross cable employed in conventional communica-
tion between ECR-ECR (See APPENDIX: RS232C CABLE).
