1 | PD_BCH | R/W | 0 | When set, the B ADC channel is powered down. The digital channels that are bound to the B ADC channel are also powered down (see the digital channel binding register).
Important notes: Set JESD_EN = 0 before changing PD_CH. To power-down both ADC channels, use MODE. If both channels are powered down, then the entire JESD204B subsystem (including the PLL and LMFC) are powered down If the selected JESD204B mode transmits A and B data on link A, and the B digital channel is disabled, link A remains operational, but the B-channel samples are undefined. |
0 | PD_ACH | R/W | 0 | When set, the A ADC channel is powered down. The digital channels that are bound to the A ADC channel are also powered down (digital channel binding register).
