During programming/debugging, the multiplexer disconnects the microcontroller pins used for programming/debugging from the target device.

This enables the programming/debugging process to be safely performed without aecting the operation of the device itself. It also prevents

external signals from aecting the programming/debugging process. When the programming/debugging process has been completed, the

multiplexer releases the microcontroller pins used for programming, so that they can be used as I/O pins or reset respectively.
