18.6.2 RESET pin

If the reset signal of the dedicated flash 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
programmer.
