Data can be written to the flash memory on-board or off-board, by using a dedicated flash programmer.
Note When using the clock out of the flash programmer, connect CLK of the programmer to X1, and connect its
Cautions 1. Be sure to connect the REGC pin in either of the following ways.
The contents of the flash memory can be rewritten after the
system. The connectors that connect the dedicated flash programmer must be mounted on the target system.
Data can be written to the flash memory with a dedicated program adapter (FA series) before the
