25.8.1 Register controlling self programming mode
25.8.2 Flow of self programming (Rewriting Flash Memory)

The self programming mode is controlled by the self programming mode control register (FPCTL).
FPCTL can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears FPCTL to 00H.
The following figure illustrates a flow of rewriting the flash memory by using a self programming library.

FPCTL
Note The FLMDPUP bit must be set to 0 (normal operation mode) while the regular user program is being executed,
and set to 1 (self programming mode) while self programming is being executed. The flash memory rewrite
circuit does not operate in normal operation mode, so even though the firmware and software for rewriting will
work, no actual rewriting will take place.
