D2 (SCLK)

Serial Data Clock.

D1 (Latch)

Latch and Shift Enable Signal. When

D1(Latch) is low, data is shifted into

D0(SDI). When D1(Latch) goes high,

the last nine bits shifted into D0(SDI)

will be used to program the addressed

configuration register. To avoid

erroneous writes to the configuration

registers, D1(Latch) should be pulled

low when NewLine is high.

D0 (SDI)

Serial Input Data. Data is valid on

D2(SCLK) rising edge. Three address

bits followed by six data bits (MSB first)

should be shifted into D0 before

D1(Latch) goes high.
