(4) RESET pin
When the reset signals of the dedicated flash memory programmer are connected to the RESET pin that is
connected to the reset signal generator on-board, a conflict of signals occurs. To avoid the conflict of signals,
isolate the connection to the reset signal generator.
When a reset signal is input from the user system in the flash memory programming mode, the programming
operation will not be performed correctly. Therefore, do not input signals other than the reset signals from the
dedicated flash memory programmer.

RESET
In the flash memory programming mode, the signal the reset signal generator
outputs conflicts with the signal the dedicated flash memory programmer outputs.
Therefore, isolate the signals on the reset signal generator side.
