8.3 Platform Dependent Macros
The following macros are used in the driver code (defined in drv_config_user.h). These macros
must be defined according to the specific hardware environment and platform. It is expected that the use
of the driver will provide these macros workable with their environment.
/*================================================*/
/* INT =======================================*/
/*================================================*/
#define IRQ_NUMBER …
/*================================================*/
/* USER SPECIFIC FUNCTION ========================*/
/*================================================*/
#define M1966_SPI_MODE_16BIT
#define M1966_DETECT_OFH_POLARITY_CHG
#define M1966_DETECT_OFH_BATT
/*================================================*/
/* PCM CLK =======================================*/
/*================================================*/

/* define PCM clock initialization macro */
#define CONFIG_HOST_PCM(void) do { \

/* FXO Reset =====================================*/
/*================================================*/
#define FXO_RESET(void) do { \
printk(“\nPerform FXO RESET\n”); \
… \
} while(0)
/*================================================*/
/*================================================*/
/* SPI =====================================*/
