IS_SPI_FIRST_BIT macro

Checks if SPI MSB LSB transmission parameter is in allowed range.

Syntax

#define IS_SPI_FIRST_BIT(__BIT__) (((__BIT__) == SPI_FIRSTBIT_MSB) || \ ((__BIT__) == SPI_FIRSTBIT_LSB))

specifies the SPI MSB LSB transmission (whether data transfer starts from MSB or LSB bit). This parameter can be a value of SPI_MSB_LSB_transmission

None
