13 DVDD power_in Low-side analog and digital power supply, 3 V to 5.5 V recommended operating range.
14 DCDC_CAP power_in Low-side input of the DC/DC converter, internally connected to the output of the primary-side LDO; absolute maximum 3.5 V to DGND.
15 DGND power_in Low-side analog and digital ground.
16 DRDY output Data ready output, active low.
17 CLKIN input Main clock input.
18 SCLK input Serial data clock input.
19 CS input Chip select input, active low.
20 DIN input Serial data input.
