(1) Conflict of signals
When the dedicated flash programmer (output) is connected to a serial interface pin (input) that is connected to
another device (output), a conflict of signals occurs. To avoid the conflict of signals, isolate the connection to
the other device or set the other device to the output high-impedance status.

Input pin
Figure 21-9. Conflict of Signals (Serial Interface Input Pin)
In the flash memory programming mode, the signal that the dedicated flash
programmer sends out conflicts with signals another device outputs.
Therefore, isolate the signals on the other device side.
