Note: Master mode must still be enabled for the Sabre to drive the DATA_CLK and DATA1 pins.

You must also select either serial mode or DSD mode in the input_select register to determine whether DATA_CLK

should be driven alone (DSD mode) or both DATA_CLK and DATA1 should be driven (serial mode). 32’d0: disables

NCO mode (default).

32’d0: disables NCO mode (default)

32’d?: enables NCO mode

EVEN_STAGE2_COEFF

Selects the symmetry of the stage 2 oversampling filter.

1’b0: Uses a sine symmetric filter (27 coefficients) (default).

1’b1: Uses a cosine symmetric filter (28 coefficients).

[1]

PROG_COEFF_WE

Enables writing to the programmable coefficient RAM.

1’b0: Disables write signal to the coefficient RAM (default).

1’b1: Enables write signal to the coefficient RAM.

[0]

PROG_COEFF_EN

Enables the custom oversampling filter coefficients.

1’b0: Uses a built-in filter selected by filter_shape (default).

1’b1: Uses the coefficients programmed via prog_coeff_data.
