19.6.2 RESET pin
If the reset signal of the dedicated flash memory programmer is connected to the RESET pin that is connected to
the reset signal generator on the board, signal collision takes place. To prevent this collision, isolate the connection
with the reset signal generator.
If the reset signal is input from the user system while the flash memory programming mode is set, the flash
memory will not be correctly programmed. Do not input any signal other than the reset signal of the dedicated flash
memory programmer.
