Interrupt 0 Polarity Select (Bit 1)
The Interrupt 0 Polarity Select bit selects the polarity for IRQ0.
1: Sets IRQ0 to rising edge
0: Sets IRQ0 to falling edge
Interrupt 0 Enable (Bit 0)
The Interrupt 0 Enable bit enables or disables IRQ0. The GPIO
bit on the interrupt Enable register must also be set in order for
this for this interrupt to be enabled.
1: Enable IRQ0
0: Disable IRQ0

Table 79. GPIO n Output Data Register
Register Description
The GPIO n Output Data register controls the output data of the
GPIO pins. The GPIO 0 Output Data register controls GPIO15 to
GPIO0 while the GPIO 1 Output Data register controls GPIO31
to GPIO16. When read, this register reads back the last data
written, not the data on pins configured as inputs (see Input Data
Register).

Table 80. GPIO n Input Data Register
Register Description
The GPIO n Input Data register reads the input data of the GPIO
pins. The GPIO 0 Input Data register reads from GPIO15 to
GPIO0 while the GPIO 1 Input Data register reads from GPIO31
to GPIO16.

Reserved
Write all reserved bits with ’0’.
Data (Bits [15:0])
The Data field[15:0] writes to the corresponding GPIO 15–0 or
GPIO31–16 pins as output data.
Data (Bits [15:0])
The Data field[15:0] contains the voltage values on the corre-
sponding GPIO15–0 or GPIO31–16 input pins.
