26.7 Programming Method
26.7.1 Controlling flash memory
26.7.2 Flash memory programming mode
memory programming mode. To set the mode, set the FLMD0 pin to V
The following figure illustrates the procedure to manipulate the flash memory.
To rewrite the contents of the flash memory by using the dedicated flash programmer, set the 78K0/LF2 in the flash
Change the mode by using a jumper when writing the flash memory on-board.
