26.6.3 Serial interface pins
the board, care must be exercised so that signals do not collide or that the other device does not malfunction.

The pins used by each serial interface are listed below.
To connect the dedicated flash programmer to the pins of a serial interface that is connected to another device on
If the dedicated flash programmer (output) is connected to a pin (input) of a serial interface connected to another
device (output), signal collision takes place. To avoid this collision, either isolate the connection with the other
device, or make the other device go into an output high-impedance state.

Figure 26-12. Signal Collision (Input Pin of Serial Interface)
In the flash memory programming mode, the signal output by the device
collides with the signal sent from the dedicated flash programmer.
Therefore, isolate the signal of the other device.
