Conflict of signals
In the flash memory programming mode, the signal that the
dedicated flash programmer sends out conflicts with signals the
other device outputs. Therefore, isolate the signals on the other
device side.
(2) Malfunction of the other device
When connecting a dedicated flash programmer (output or input) to a serial interface pin (input or output)
connected to another device (input), the signal output to the other device may cause the device to
malfunction. To avoid this, isolate the connection to the other device or make the setting so that the input
signal to the other device is ignored.
