Table 26
5.4.2
Following a falling edge of CS#, the first eight bits received on DIN specify the type of
command. The data bytes following a write command are stored in the selected
configuration registers or the selected part of the Coefficient RAM. The number of data
bytes depends on the type of command. After every command CS# must be set to ’1’.

5.4.3
If the first eight bits received via DIN represent a read command, the SICOFI
initiate its response via DOUT. An identification byte (81
number of data bytes (contents of configuration registers or contents of the CRAM).
During execution of a read command, the device will ignore data on DIN. After every
command CS# must be set to ’1’.
