Macro Definition Documentation

I2C_CMD_RESERVED

#define I2C_CMD_RESERVED   (32)

Common I2C_control command code reservation offset. I2C driver implementations should offset command codes with I2C_CMD_RESERVED growing positively

Example implementation specific command codes:

#define I2CXYZ_CMD_COMMAND0      I2C_CMD_RESERVED + 0
#define I2CXYZ_CMD_COMMAND1      I2C_CMD_RESERVED + 1

I2C_STATUS_RESERVED

#define I2C_STATUS_RESERVED   (-32)

Common I2C_control status code reservation offset. I2C driver implementations should offset status codes with I2C_STATUS_RESERVED growing negatively.

Example implementation specific status codes:

#define I2CXYZ_STATUS_ERROR0     I2C_STATUS_RESERVED - 0
#define I2CXYZ_STATUS_ERROR1     I2C_STATUS_RESERVED - 1
#define I2CXYZ_STATUS_ERROR2     I2C_STATUS_RESERVED - 2
