Description
GPIO data types – this is the GPIO data returned from the M1X22_GPIO_DATA_GET access command,
or data to be written to the GPIO port using the M1X22_GPIO_DATA_SET access command.
Prototype
typedef enum
{
M1X22_GPIO_DATA_LOW = 0, /* GPIO data - low */
M1X22_GPIO_DATA_HIGH = 1 /* GPIO data - high */
}
M1X22_GPIO_DATA_TYPE;
Parameters
Name Value Description
M1X22_GPIO_DATA_LOW
0
GPIO data – low.
M1X22_GPIO_DATA_HIGH
1
GPIO data – high.
7.12.6 M1X22_GPIO_SIGNAL_DIRECTION
Description

Prototype
typedef enum {
M1X22_GPIO_DIR_INPUT = 0, /* GPIO pin signal direction – INPUT */
M1X22_GPIO_DIR_OUTPUT = 1 /* GPIO pin signal direction - OUTPUT */
}
M1X22_GPIO_SIGNAL_DIRECTION;
Parameters
Name Value Description
M1X22_GPIO_DIR_INPUT
0
GPIO pin signal direction – INPUT.
M1X22_GPIO_DIR_OUTPUT
1
GPIO pin signal direction – OUTPUT.
