unsigned int spi_options_t::baudrate

Preferred baudrate for the SPI.

Definition at line 78 of file spi.h.

Referenced by getBaudDiv(), init_spiMaster(), and init_spiSlave().

unsigned char spi_options_t::bits

Number of bits in each character (8 to 16).

Definition at line 81 of file spi.h.

Referenced by init_spiMaster(), init_spiSlave(), and spi_setupChipReg().

unsigned char spi_options_t::modfdis

Disables the mode fault detection.

With this bit cleared, the SPI master mode will disable itself if another master tries to address it.
