rxclk_ena : Master rxclk enable. When set, the chip’s rxclk is enabled, when cleared, rxclk is disabled.
All tristates are ACTIVE LOW so a ‘0’ turns on the output and a ‘1’ tristates it.
tristate(10) : This bit turns on the dvga_d outputs.
tristate(9) : This bit turns on the dvga_c outputs.
tristate(8) : This bit turns on the dvga_b outputs.
tristate(7) : This bit turns on the dvga_a outputs.
tristate(6) : This bit turns on the rx_sync_out_6/7, and the rxout_6/7_a/b/c/d outputs.
tristate(5) : This bit turns on the rx_sync_out_4/5, and the rxout_4/5_a/b/c/d outputs.
tristate(4) : This bit turns on the rx_sync_out_2/3, and the rxout_2/3_a/b/c/d outputs.
tristate(3) : This bit turns on the rx_sync_out_0/1, and the rxout_0/1_a/b/c/d outputs.
tristate(2) : unused
tristate(1) : rxclk_out
tristate(0) : interrupt, and rx_sync_out.

rx_oneshot : When set, a one shot pulse is sent to the receive blocks for syncing. This only works if the
blocks are programmed to use the oneshot as the sync source. To use the oneshot again, it
must be programmed back to a ‘0’ and then back to a ‘1’.
