Description
GPIO data types – this is the GPIO data returned from the M1966_GPIO_DATA_GET access command,
or data to be written to the GPIO port using the M1966_GPIO_DATA_SET access command.
Prototype
typedef enum
{
M1966_GPIO_DATA_LOW = 0, /* GPIO data - low */
M1966_GPIO_DATA_HIGH = 1 /* GPIO data - high */
}
M1966_GPIO_DATA_TYPE;
Parameters
Name Value Description
M1966_GPIO_DATA_LOW
0
GPIO data – low.
M1966_GPIO_DATA_HIGH
1
GPIO data – high.
