Figures 43 and 44 illustrate WRITE and READ operations to register addresses via an 8-bit SPI controller. These
operations are performed as a 3-byte transfer. CS is asserted between each byte which is required for CS to be
asserted before the first falling edge of SCLK after the DATA byte to indicate to the state machine that one byte
should be transferred. The state of SDI is a “don’t care” during the DATA byte of a read operation.
