Figures 42 and 43 illustrate the timing relationships for
2-byte and N-byte transfers, respectively. The opera-
tion for a 3-byte transfer can be inferred from these
diagrams.
SPI Configuration
Address 0x00: chip_port_config
Bit ordering and SPI reset are controlled by this regis-
ter. Bit order can be selected as MSB to LSB (MSB first)

LSB First
Setting this bit high configures the SPI to inter-
pret serial data as arriving in LSB to MSB order.
Soft Reset
Setting this bit high resets all SPI registers to
default values.
Reserved
This bit should always be set high.
avoid ambiguity in bit ordering.
