5.3Output Data Register (OUT_DATA)

The GPIO output data register (OUT_DATA) indicates the value to be driven on a given GPIO output pin. The OUT_DATA registers are shown in Figure 5 and described in Table 5.

Table 5.	Output Data Register (OUT_DATA) Field Descriptions
Bit	Field	Value	Description
31−16	Reserved	0	Reserved. The reserved bit location is always read as 0. A value written to
			this field has no effect.
15−0	OUTn		Controls the drive state of the corresponding GPn pin. These bits do not
			affect the state of the pin when the pin is configured as an input. Reading
			these bits returns the value of this register, not the state of the pin.
