Level Detector
An input level detector is provided to monitor the signal level
on any of the input busses. The input bus, input format, and
the level detection type are programmable (see
EN
Microprocessor Interface , GWA registers F804h, F805h and
F806h). This signal level represents the wideband signal from
the A/D and is useful for controlling gain/attenuation blocks

ahead of the converter.
The supported monitoring modes include integrated
magnitude (like the HSP50214 w/o the threshold) and leaky
integration (Y n = X n x A + Y n-1 x (1-A)) where A = 1, 2 -8 , 2 -12 ,
or 2 -16 (see GWA = F805h). The measurement interval can
be programmed from 2 to 65537 samples (or continuous for
the leaky integrator case). The output is 32 bits and is read via
the μ P interface.
Note that the accumulators in the input level detector are 32
