RCD CS Calibration
RCD has two channels: CHA, and CHB. The calibration is performed in parallel for both the channels. Before starting the CS calibration the RCD device is kept in DCS training mode.
RCD CA Calibration
RCD has two channels: CHA and CHB. The calibration is performed in parallel for both the channels. Before starting the CA calibration the RCD device is kept in DCA training mode. In this mode all the CA bits are XORed, and sampled on the rising edge of CK when CS is asserted, and status of them is looped back on QLBx or ALERT_n pin. This calibration stage uses odelays of the ca lines, ca bit slips, and tx 90 phase shift of the ca lines.
