ending with the LSB, D0. Each incoming command message

described in Table 7 . The 5 bits D15 : D11, called register
address bits, are used to select the command register. Bit

requirements.
D10 is the watchdog bit. The remaining 10 bits, D9 : D0, are
used to configure and control the output and its protection
features. Multiple messages can be transmitted in

succession to accommodate those applications where daisy
chaining is desirable or to confirm transmitted data as long as
the messages are all multiples of 16 bits. Any attempt made
to latch in a message that is not 16 bits will be ignored.
All SPI registers are reset (all bit equal 0) in case of RST
equal 0 or fail mode (Fail=1).
DEVICE REGISTER ADDRESSING
The register addresses (D15 : D11) and the impact of the
serial input registers on device operation are described in this
section. Table 8 summarizes the SI registers.
