Notes: (1). TBCLK and RBCLK must be frequency locked to QCLK though they may have independent phase relationships to QCLK
and to one another.
(2). TBCLK polarity (edge sensitivity) is programmable through the CU Interface Modes Register [cu_interface_modes
0x06].

Note:
TBCLK and RBCLK polarities are programmable through the CU Interface Modes register. The figure depicts both clocks
programmed to falling-edge active.
