Evaluation bits. Bits EV2, EV1 and EV0 are special control bits for
manufacturer’s evaluation and must always be kept at their default values for
normal operation of UDA1380; default value 000.
default value 0
ADC clock enable. A 1-bit value to enable the system clock (from SYSCLK
input) to the analog part of the ADC. See Fig.5 for more detailed information.
When this bit is logic 0: clock to ADC disabled and when this bit is logic 1: clock
to ADC running. Default value 0.
Decimator clock enable. A 1-bit value to enable the 128f
decimator, the 128f
L3-bus or I
bit is logic 0: clock to the decimator disabled. When this bit is logic 1: clock to
the decimator running. Default value 1.
FSDAC clock enable. A 1-bit value to enable the 256f
of the FSDAC. See Fig.5 for more detailed information. When this bit is logic 0:
clock to FSDAC disabled. When this bit is logic 1: clock to the FSDAC running.
Default value 0.
Interpolator clock enable. A 1-bit value to enable the 128f
interpolator, the 128f
registers of the L3-bus or I
information. When this bit is logic 0: clock to the interpolator disabled. When
this bit is logic 1: clock to the interpolator running. Default value 1.
default value 00
ADC clock select. A 1-bit value to select the 128f
analog part for the decimator and the ADC. This can either be the clock derived
from the SYSCLK input or from the WSPLL. When this bit is logic 0: SYSCLK
is used. When this bit is logic 1: WSPLL is used. Default value 0.
