FLMD0 38-A
−
Connect to V
SS.
Note
RESET 2 Input
Connect directly to V
DD
or via a resistor.
Note
FLMD0 is a pin that is used to write data to the flash memory. To rewrite the data of the flash memory on-
board, connect this pin to V
SS
via a resistor (10 k
Ω
: recommended). The same applies when executing on-
chip debugging with a product with an on-chip debug function.
