33.5.4 Flash functions
33.5.5 Pin processing
(1) FLMD0 pin
Caution Make sure that the FLMD0 pin is at 0 V when reset is released.
The FLMD0 pin is used to set the operation mode when reset is released and to protect the flash memory from
being written during self rewriting. It is therefore necessary to keep the voltage applied to the FLMD0 pin at 0
V when reset is released and a normal operation is executed. It is also necessary to apply a voltage of V
level to the FLMD0 pin during the self programming mode period via port control before the memory is
rewritten.
When self programming has been completed, the voltage on the FLMD0 pin must be returned to 0 V.
