SFORI[2:0]
Digital data input formats. A 3-bit value to select the digital input data
format (DATAI input). Default value 000, see Table 23.
7
default value 0
6SEL_SOURCE
Digital output interface mode settings. A 1-bit value SEL_SOURCE to set
the mode of the digital output interface source to either the decimator output
or the digital mixer output. When this bit is logic 0: source digital output
interface mode set to decimator. When this bit is logic 1: source digital output
interface mode set to digital mixer output. Default value 0.
5
default value 0
4SIM
Digital output interface mode settings. A 1-bit value SIM sets the mode of
the digital output interface. The speed of the BCKO pad, being 64fs or 48fs, is
selected by the bits sys_div[1:0]. In case the 384fs or 768fs mode is selected
the output clock is 48fs, in case 256fs or 512fs is selected, the BCKO is 64fs.
When this bit is logic 0: mode of digital output interface is set to slave. When
this bit is logic 1: mode of digital output interface is set to master. Default
value 0.

default value 0
2 to 0
SFORO[2:0]
Digital data output formats. A 3-bit value to set the digital data output format
(on pin DATAO). Default value 000, see Table 24.
