BECTL
Even if the FLMD0 pin is not controlled externally, it can be controlled by software with the BECTL register to set
the self-programming mode.
However, depending on the processing of the FLMD0 pin, it may not be possible to set the self-programming
mode by software. When using BECTL, leaving the FLMD0 pin open is recommended. When pulling it down
externally, use a resistor with a resistance of 100 kΩ or more. In addition, in the normal operation mode, use
BECTL with the pull down selection. In the self-programming mode, the setting is switched to pull up in the self-
programming library.
The BECTL register is set by a 1-bit or 8-bit memory manipulation instruction.
Reset input sets this register to 00H.
