GPIO Direction 5-0 (GPDIR[5:0])
These bits set the input/output direction of the GPIO pins.
0: GPIO pin is configured as an input
1: GPIO pin is configured as an output
RESERVED
GPIO Data 5-0 (GPIOD[5:0])
When a GPIO pin is enabled as an output, the value written to this field is
output on the corresponding GPIO pin. Upon a read, the value returned
depends on the current direction of the pin. If the pin is an input, the data
reflects the current state of the corresponding GPIO pin. If the pin is an
output, the data is the value that was last written into this register. The pin
direction is determined by the GPDIR bits of this register.
General Purpose I/O Data & Direction Register (GPIO_DATA_DIR)
This read/write register configures the direction of the GPIO pins and contains the GPIO input and
output data bits.
