23.4.5
If any of the FBS, CLKP, IDIV or CLKC bit values are changed, then the HSPI software reset is
generated. The receive and transmit FIFO pointers can be initialized by the HSPI software reset.
The data transmission after the HSPI software reset should protect transmitting and receiving
protocol of HSPI, and please perform it from the first. A guarantee of operation is not offered
other than it.
23.4.6
SPCR also allows the user to define the shift timing for transmit data and polarity. The FBS bit in
SPCR allows selection between two different transfer formats. The MSB or LSB is valid on the
falling edge of HSPI_CS. The CLKP bit in SPCR allows for control of the polarity select block
which controls which edges of HSPI_CLK shift and sample data in the master and slave.
23.4.7
The master and slave can be considered linked together as a circular shift register synchronized
with HSPI_CLK. The transmit byte from the master is replaced with the receive byte from the
slave in eight HSPI_CLK cycles. Both the transmit and receive functions are double buffered to
allow for continuous reads and writes. When FIFO mode is enabled eight entry FIFOs are
available for both transmit and receive data.
