NCO-Related Registers
4-11
MASK_SYNCOK
1
If this bit is 1, a missing SYNCOK does not generate an
interrupt. If this bit is 0, a missing SYNCOK generates an
interrupt. The reset value is 0.
MASK_FIFO_ALARM
0
If this bit is 1, a FIFO alarm (pointer collision) does not
generate an interrupt. If this bit is 0, a FIFO alarm
(pointer collision) generates an interrupt. The reset value
is 0.
4.2.2 Register 13
RES
Reserved
This bit is reserved.
R 7
BELOW_THRES
FIFO CONTENT THRESHOLD
When this bit is 1, the virtual FIFO content is below or
equal to the threshold programmed in Register 43.
During AUTO_ACQUISITION, the threshold is
dynamically changed. The reset value is 0.
MEASUREMENT_DONE
A 1 in this bit indicates that the measurement data gained
during byte clock probe are valid and that the
measurement is complete. The reset value is 0.
STEP_UPDATE
A 1 in this bit indicates a step update since the last
reading of the register. This is relevant only during NCO
acquisition mode. The reset value is 0.
AUTO_ACQUI_RUNNING
A 1 in this bit indicates that the internal frequency
acquisition is running. The reset value is 0.
ACQ_STATE
Internal Acquisition State
This indicates how many auto acquisition loops have
taken place since the initiation of the auto acquisition
mode. The reference duration has a length of two
ACQ_STATE input packets, and the threshold is divided
by two ACQ_STATE times. The reset value is 0b111.
