CLK6 Synthesizer Select
Selects the clock output CLK6 derived from synthesizer G₆ (T0), synthesizer F or synthesizer G_T4 (T4). Com-
posite signal, Frame8K, and Frame2K are all produced at synthesizer F. When synthesizer F is selected, sets
bit7~bit6 of the register Frame_Mux to select frame pulse clock from composite signal, Frame8K, or Frame2K.
Signal level of CLK6 is LVCMOS.

CLK7 Synthesizer Select
Selects the clock output CLK7 derived from synthesizer G₇ (T0), synthesizer F or synthesizer G_T4 (T4). Com-
posite signal, Frame8K, and Frame2K are all produced at synthesizer F. When synthesizer F is selected, sets
bit9~bit8 of the register Frame_Mux to select frame pulse clock from composite signal, Frame8K, or Frame2K.
Signal level of CLK7 is LVCMOS.
