4.2.7.32 GPIO Port C Direction (GPCDIR) Register

The GPIO Port C Direction (GPCDIR) Register is shown and described in the figure and table below.

General-Purpose Input/Output (GPIO)

Controls direction of GPIO Port A pins when the specified pin is configured as a GPIO in the

appropriate GPAMUX1 or GPAMUX2 register.

Configures the GPIO pin as an input. (default)

Configures the GPIO pin as an output

The value currently in the GPADAT output latch is driven on the pin. To initialize the GPADAT

latch prior to changing the pin from an input to an output, use the GPASET, GPACLEAR, and

GPATOGGLE registers.

Figure 4-72. GPIO Port B Direction (GPBDIR) Register

Controls direction of GPIO pin when GPIO mode is selected. Reading the register returns the

current value of the register setting

Configures the GPIO pin as an input. (default)

Configures the GPIO pin as an output
