Data are shifted on the falling edge of DCLK. This output is high impedance when CS is high. 13 A5 1 BUSY Busy Output. This output is high impedance when CS is high. 14 A4 2 DIN Serial Data Input. If CS is low, data sre latched on the rising edge of DCLK. 15 A3 3 CS Chip Select Input. Controls conversion timing and enables the serial input/output register. CS high = power-down mode (ADC only). 16 A2 4 DCLK External Clock Input. This clock runs the SAR conversion process and synchronizes serial data I/O. |
