Symbol Tracking Lag
DESCRIPTION
These bits set the lead gain exponent as given by:
Symbol Tracking Lead Gain Exponent = 2 -(32-E),
where E corresponds to the 5-bit binary value programmed here. Thus, a gain range from
2 -1 to 2 -32 relative to the MSB position of the NCO control word may be achieved for E = 11111 to 00000
Binary. Bit position 13 is the MSB.
Format same as lead gain mantissa. Bit position 8 is the MSB.
Format same as lead gain exponent. Bit position 4 is the MSB.

FUNCTION
Symbol Tracking Loop
Filter Lag Accumulator
Initialization
39
DESCRIPTION
Writing to this address initializes the lag accumulator with the contents of the four Microprocessor
Interface Holding Registers at the start of the next loop filter computation cycle. The contents of the
holding registers should not be changed until after the start of a new compute cycle since the current
contents of the holding registers are loaded at the compute cycle start. At a slow rate, it could take 1 low
rate symbol time to change. The Microprocessor Interface should be used to read an internal status
register which signals when the lag accumulator load is complete (see Table 13 in the “Microprocessor
Interface” on page 27). The contents of the holding registers are loaded into the 32 MSBs of the lag
accumulator and the 8 LSBs are zeroed.
It is a good practice to load the LAG accumulators at the very end of a configuration load sequence.
