GREG22: Global Loopback Control and PLL Power Down, Read/Write (35H/B5H)
The Level Meter Channel Select bits (CS[1:0]) select a channel, data on which will be level metered.
CS[1:0] = 00:
CS[1:0] = 01:
CS[1:0] = 10:
CS[1:0] = 11:
The PLL Power Down bit (PPD) controls the operation state of the PLL block.
PPD = 0:
PPD = 1:
The Loop Control bits determine the loopback status. Refer to
