typename SelfType::ValueType fifo_read_downsampling_multiplier_minus_one ()

Downsampling multiplier (reciprocal of the downsampling ratio) of the

Encoder-Transmitter FIFO reading pixel data from the encoder, minus one.

A downsampling multiplier of N means that the FIFO performs a read

operation once every N cycles of the "read clock" (rd_clk), which is

possibly the encoder clock.

It's preferred to use the `fifo_read_downsampling_multiplier()` and

`set_fifo_read_downsampling_multiplier()` helper methods to get / set its

value.

typename SelfType::ValueType fifo_write_downsampling_multiplier_minus_one ()

Downsampling multiplier (reciprocal of the downsampling ratio) of the

Encoder-Transmitter FIFO writing pixel data to the transmitter, minus one.

A downsampling multiplier of N means that the FIFO performs a write

operation once every N cycles of the "write clock" (wr_clk), which is

possibly the HDMI transmitter pixel clock.

It's preferred to use the `fifo_write_downsampling_multiplier()` and

`set_fifo_write_downsampling_multiplier()` helper methods to get / set its

value.

typename SelfType::ValueType is_dvi_clock_polarity_positive ()

If true, the polarity of the clock output to the external DVI interface

(not the internal HDMI interface) is positive (active high).

None of the Amlogic SoCs we use (S905D2, A311D and S905D3) support

external DVI interfaces. Amlogic-provided code always sets this bit to 0.

It's preferred to use `dvi_clock_polarity()` and `set_dvi_clock_polarity()`

helper methods to get / set its value.
