4.5.1.4 PSELRESET[n] (n=0..1)

Address offset: 0x200 + (n × 0x4)

Mapping of the nRESET function (see POWER chapter for details)

All PSELRESET registers have to contain the same value for a pin mapping to be valid. If values are not

the same, there will be no nRESET function exposed on a GPIO. As a result, the device will always start

independently of the levels present on any of the GPIOs.
