3-2-4. Memory Maps
This Section gives code and data memory maps for the various JOB60851 operation modes.
(1)Download mode
This mode maps the code memory to the EPROM and the data memory to program RAM and Flash memory. It uses the loader, a program stored in the EPROM, to download a user application program over a serial link from the development host to program RAM.
