Data Fields
void *	rx_buf
	Buffer for receive data.

const void *	tx_buf
	Buffer for transmit data.

size_t	len
	Length of receive and transmit buffers in bytes.

uint32_t	speed_hz
	Sets the bit-rate of the device.

uint16_t	delay_usecs
	Sets the delay after a transfer before the chip select status is changed and the next transfer is triggered.

uint8_t	bits_per_word
	Sets the device wordsize.

uint8_t	cs_change
	If true, device is deselected after transfer ended and before a new transfer is started.

uint8_t	rx_nbits
	Amount of bits that are used for reading.

uint8_t	tx_nbits
	Amount of bits that are used for writing.

uint32_t	mode
	Sets one of the possible modes that can be used for SPI transfers (dependent on clock phase and polarity).

uint8_t	cs
