4. Writing new application program
Next, the new application program in the host is
written into the erased flash memory blocks. Do
not write to unerased blocks.
1. Initial state
The FWP assessment program that confirms that
user program mode has been entered, and the
program that will transfer the programming/erase
control program from flash memory to on-chip
RAM should be written into the flash memory by
the user beforehand. The programming/erase
control program should be prepared in the host
or in the flash memory.
2. Programming/erase control program transfer
When user program mode is entered, user
software confirms this fact, executes transfer
program in the flash memory, and transfers the
programming/erase control program to RAM.
