SPI COMMAND SUMMARY
Table below provides a comprehensive list of SPI
commands recognized by the 33975 and the reset state of
each register. Table 16 and Table 17 contain the Serial
Output (SO) data for input voltages greater or less than the
threshold level. Open switches are always indicated with a
logic [0], closed switches are indicated with logic [1].
