Supply, reset and clock management
38/136
This 16-bit register is read/write by software but can be written only once between two reset
events. It is cleared by hardware after a reset; When both MUXCR0 and MUXCR1 registers
are at 00h, the multiplexed PA3/RESET pin will act as RESET. To configure this pin as
output (Port A3), write 55h to MUXCR0 and AAh to MUXCR1.
These registers are one-time writable only.

To configure PA3 as general purpose output:
After power-on / reset, the application program has to configure the I/O port by writing
to these registers as described above. Once the pin is configured as an I/O output, it
cannot be changed back to a reset pin by the application code.
To configure PA3 as RESET:
An internally generated reset (such as POR, LVD, WDG, illegal opcode) will clear the
two registers and the pin will act again as a reset function. Otherwise, a power-down is
required to put the pin back in reset configuration.
