SDO is tristated whenever ENN is inactive (high) or CSN is inactive (high).
Using the SPI interface
The SPI interface allows either cascading of multiple devices, giving a longer shift register, or working
with a separate chip select signal for each device, paralleling all other lines. Even when there is only
one device attached to a CPU, the CPU can communicate with it using a 16 bit transmission. In this
case, the upper 4 bits are dummy bits.
SPI Filter
To prevent spikes from changing the SPI settings, SPI data words are only accepted, if their length is
at least 12 bit.
