D0 Each VR has its own VR latch that holds its programmed
resistance value. These VR latches are updated from an internal
serial-to-parallel shift register that is loaded from a standard
3-wire serial-input digital interface. Eleven data bits make up
the data-word clocked into the serial input register. The first
three bits are decoded to determine which VR latch is loaded
with the last eight bits of the data-word when the CS strobe is
returned to logic high. A serial data output pin at the opposite
end of the serial register (AD5204 only) allows simple daisy
chaining in multiple VR applications without requiring
additional external decoding logic. Rev. D A4 …
