Document #: 38-08014 Rev. *H Page 45 of 85

The GPIO 0 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 GPIO19. When read, this register reads back the last data written,

not the data on pins configured as inputs (see Input Data Register).

Writing a 1 to any bit will output a high voltage on the corresponding GPIO pin.

Reserved

All reserved bits must be written as ‘0’.

GPIO 1 Output Data Register [0xC024] [R/W]
