4.13 M1966_GPIO_SIGNAL_DIRECTION

Description

GPIO pin signal direction. This control bit is used to designate the GPIO pin as either input or output.

Prototype

typedef enum {

M1966_GPIO_DIR_INPUT = 0, /* GPIO pin signal direction – INPUT */

M1966_GPIO_DIR_OUTPUT = 1 /* GPIO pin signal direction - OUTPUT */

}

M1966_GPIO_SIGNAL_DIRECTION;

Parameters

Name Value Description

M1966_GPIO_DIR_INPUT

GPIO pin signal direction – INPUT

M1966_GPIO_DIR_OUTPUT

GPIO pin signal direction - OUTPUT

4.14 M1966_GPIO_INTR_POLARITY

Description

GPIO Interrupt signal transition edge selection. The defines the interrupt source as being either on a

rising or a falling edge of the corresponding GPIO pin. If configured as M1966_GPIO_POL_RISING a

rising edge will trigger an interrupt from the corresponding GPIO pin. If configured as

M1966_GPIO_POL_FALLING a falling edge will trigger an interrupt from the corresponding GPIO pin.

Prototype

typedef enum {

M1966_GPIO_POL_RISING = 0, /* Sig transition edge polarity - RISING */

M1966_GPIO_POL_FALLING = 1 /* Sig transition edge polarity - FALLING */

}

M1966_GPIO_INTR_POLARITY;

Parameters

Name Value Description

M1966_GPIO_POL_RISING

Interrupt edge selection - RISING

M1966_GPIO_POL_FALLING

Interrupt edge selection - FALLING
