SFORI[2:0]
default value 00000
Digital data input formats. A 3-bit value to select the digital input data
format (DATAI input).
Default value 000, see Table 23.
default value 0
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.
default value 0
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 64f
s
or 48f
s
, is
selected by the bits sys_div[1:0]. In case the 384f
s
or 768f
s
mode is selected
the output clock is 48f
s
, in case 256f
s
or 512f
s
is selected, the BCKO is 64f
s
.
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
Digital data output formats.
A 3-bit value to set the digital data output format
(on pin DATAO). Default value 000, see Table 24.
