The Serial Peripheral Interface (SPI) is selected if IM(1:0) is strapped to ´10
The SPI interface of the OctalFALC

of a read or write operation is marked by the falling edge of the chip select signal CS
whereas the end of the operations is marked by the rising edge of CS. Because of CS
the SPI interface has no slave address.
The first bit of the serial data in (SDI) is ´1
operation. The first four bits of the 15 bit address are not valid for the OctalFALC
In read operation the OctalFALC
register at the serial data out (SDO).
In general SPI data are driven with the negative edge of the serial clock (SCLK) and
sampled with the positive edge of SCLK.
