Macro Definition Documentation

EMAC_CMD_RESERVED

#define EMAC_CMD_RESERVED   32

Common EMAC_control command code reservation offset. EMAC driver implementations should offset command codes with EMAC_CMD_RESERVED growing positively

Example implementation specific command codes:

#define EMACXYZ_CMD_COMMAND0     EMAC_CMD_RESERVED + 0
#define EMACXYZ_CMD_COMMAND1     EMAC_CMD_RESERVED + 1

EMAC_STATUS_RESERVED

#define EMAC_STATUS_RESERVED   -32

Common EMAC_control status code reservation offset. EMAC driver implementations should offset status codes with EMAC_STATUS_RESERVED growing negatively.

Example implementation specific status codes:

#define EMACXYZ_STATUS_ERROR0    EMAC_STATUS_RESERVED - 0
#define EMACXYZ_STATUS_ERROR1    EMAC_STATUS_RESERVED - 1
#define EMACXYZ_STATUS_ERROR2    EMAC_STATUS_RESERVED - 2
