BITS
11:0
RESERVED
GPIO Direction 11-0 (GPIODIR[11:0])
These bits set the input/output direction of the 12 GPIO pins.
0: GPIO pin is configured as an input
1: GPIO pin is configured as an output
RESERVED
GPIO Data 11-0 (GPIOD[11:0])
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. For
GPIOs 11-10 and 7-0, the pin direction is determined by the GPDIR bits of
this register. For GPIOs 9 and 8, the pin direction is determined by the
GPDIR bits and the 1588_GPIO_OE bits in the
Configuration Register
General Purpose I/O Data & Direction Register (GPIO_DATA_DIR)
This read/write register configures the direction of the 12 GPIO pins and contains the GPIO input and
output data bits.
Offset:
(GPIO_CFG).
