16.6.16 GPIO Pin Data Output Registers (SIU_GPDO0_3 –
SIU_GPDO412_413)
The SIU_GPDOx_x registers are written to by software to drive data out on the external GPIO pin. Each
byte of a register drives a single external GPIO pin, which allows the state of the pin to be controlled
independently from other GPIO pins. Writes to the SIU_GPDOx_x registers have no effect on pin states if
the pins are configured as inputs by the associated Pad Configuration Registers. The SIU_GPDOx_x
register values are automatically driven to the GPIO pins without software update if the direction of the
GPIO pins is changed from input to output.
Writes to the SIU_GPDOx_x registers have no effect on the state of the corresponding pins when the pins
are configured for their primary function by the corresponding PCR.
