Detailed Description

These SPI macros are reservations for SPI.h

Macro Definition Documentation

#define SPI_CMD_RESERVED   32

Common SPI_control command code reservation offset. SPI driver implementations should offset command codes with SPI_CMD_RESERVED growing positively

Example implementation specific command codes:

#define SPIXYZ_CMD_COMMAND0     SPI_CMD_RESERVED + 0
#define SPIXYZ_CMD_COMMAND1     SPI_CMD_RESERVED + 1

#define SPI_STATUS_RESERVED   -32

Common SPI_control status code reservation offset. SPI driver implementations should offset status codes with SPI_STATUS_RESERVED growing negatively.

Example implementation specific status codes:

#define SPIXYZ_STATUS_ERROR0    SPI_STATUS_RESERVED - 0
#define SPIXYZ_STATUS_ERROR1    SPI_STATUS_RESERVED - 1
#define SPIXYZ_STATUS_ERROR2    SPI_STATUS_RESERVED - 2
