(7) Power supply
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.
When the system shifts to the flash memory programming mode, all the pins that are not used for flash
memory programming are in the same status as that immediately after reset. If the external device connected
to each port does not recognize the status of the port immediately after reset, pins require appropriate
processing, such as connecting to V
Connect X1, X2, XT1, XT2, and REGC in the same status as that in the normal operation mode.
During flash memory programming, input a low level to the DRST pin or leave it open. Do not input a high
level.
Supply the same power (V

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.
