During programming, the multiplexer disconnects the
microcontroller pins used for programming from the target
device. This enables the programming process to be safely
performed without affecting the operation of the device itself. It
also prevents external signals from affecting the programming
process. When the programming process has been completed,
the multiplexer releases the microcontroller pins used for
programming so that they can be used as I/O pins.
When the programming process has been completed, the
multiplexer releases the microcontroller pins used for
programming, thus enabling them to be used as I/O pins. This
also enables the programmer to remain connected to the target
device without affecting its operation.
