Detailed description

command byte followed by some data bytes whose direction depends on the type of
command. If the command byte requires some data to be read from the register file, those
data are transmitted from the slave to the master through the MISO pin; thus the master
appends a number of NOPs (0x00) to the command, so that the entire data can be
transmitted,
If the SS wire goes high before the completion of a command byte in the data frame, the
SPV1020 rejects that byte and the frame is closed; then the next data frame is considered
as a new one, starting with a command byte.
Figure 4.
The host can insert a short pause between each frame byte, or it can work in burst mode
(no pause between frame bytes).
Some data words can be longer than 8 bits, such as ADC results (10 bits); in such cases,
data is first extended to the nearest multiple of one byte (it is right justified), then it is split
into bytes, e.g. the ADC result R is formatted as follows:
