The loading of the Reference and Mask Registers may be
done simultaneously by setting A0-2 = 000, setting the
DREF and DCONT inputs to their proper values and pulsing
RLOAD and CLOAD low. In this configuration, DREF7 loads
the reference data and DCONT7 loads the mask
information; both sets of data are loaded serially. It will take
256 load pulses (RLOAD) to load the reference array, and
256 CLOAD pulses to load the mask array. Upon completion
of the mask and register loading, TXFR is pulsed low, which
transfers the reference and control data from the preload
registers to the Reference and Mask Registers, updating the
data that will be used in the correlation. Reference and mask
data can be loaded more quickly by configuring the
correlator as an 8 row by 32 sample array, loading the bits
eight at a time, then changing the configuration back to 1 x
256 to perform the correlation.
