SPI and MICROWIRE Interface
When using the SPI (Figure 10a) or MICROWIRE (Figure
10b) interfaces, set CPOL = 0 and CPHA = 0 in the SPI
master. Conversion begins with a falling edge on
CS
.
Three consecutive 8-bit readings are necessary to
obtain the entire 12-bit result from the ADC. DOUT data
transitions on the serial clock
’
s falling edge. The first 8-
bit data stream contains all leading zeros. The second
8-bit data stream contains a leading zero followed by
the MSB through D5. The third 8-bit data stream con-
tains D4
–
D0 followed by trailing zeros.
