SPI COMMAND SUMMARY
control bits and 12 command data bits. There are 12 separate
commands that are used to set operational parameters of
device. The operational parameters are stored internally in
16 bit registers.
internal registers at POR. SPI commands may be sent to the
device at any time in NORMAL STATE.
