Core components

4.5.1.60 PSELRESET[0]

Address offset: 0x200

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.
