DESCRIPTION
Reserved.
0- The SYNCIN2 pin has no effect on the halfband and FIR filters.
1- When the SYNCIN2 pin is asserted, the filter control circuitry in the halfband filters, the FIR, the
resampler, and the discriminator are reset. SYNCIN2 can be used to synchronize the computations of
the filters in multiple parts for the alignment (see Synchronization Section).
1- Bypass Halfband Filters.
0- Enable HB Filters (at least one HB must be enabled).
0- Disables HB number 5 (the last in the cascade).
1- Enables HB filter number 5.
Setting this bit enables HB filter number 4.
Setting this bit enables HB filter number 3.
Setting this bit enables HB filter number 2.
Setting this bit enables HB filter number 1.

DESCRIPTION
Reserved.
When this bit is 1, the SYNCIN2 pin loads the contents of the master registers into the AGC accumulator.
The magnitude measurement out of the cartesian to polar converter is subtracted from this value to get
the gain error. A gain of 1.647 in the cartesian to polar conversion that must be taken into account when
computing this threshold. These bits are weighted -2 2 down to 2 -10 . Bit 28 is the MSB.
Selected when AGCGNSEL = 1. These bits, MMMM, together with the exponent bits, EEEE (11-8), set
the loop gain for the AGC loop. The gain adjustment per output sample is:
1.5dB (Threshold -[Magnitude * 1.6]) 0.MMMM * 2 -(15 - EEEE) where magnitude ranges from 0 to 1.414
and the threshold is programmed in bits 28-16. The decimal value for the mantissa is calculated as
DEC(MMMM)/16. Bit 15 is the MSB.
Selected when AGCGNSEL = 1. These bits are EEEE. See description of bits 15-12. Bit 11 is the MSB.
Selected when AGCGNSEL = 0. These bits are MMMM. See description for bits 15-12. Same equations
are used for Loop 0. Bit 7 is the MSB.
Selected when AGCGNSEL = 0. These bits are EEEE. See description for bits 15-12. Same equations
are used for Loop 0. Bit 3 is the MSB.
