Table 37
DM1 and DM0 digital equalizer mode of
operation.
Notes
1.
In normal mode the main data channels and the AUX
channel are processed (equalized), the AUX channel
envelope information is not processed.
In search mode only the AUX channel is processed by
the digital equalizer.
Off means that the digital equalizer is put to sleep (low
power), this can be used for example in portable
recording equipment. RDSYNC is HIGH if off mode.
Also note that the other digital equalizer registers are
not addressable while the digital equalizer is in off
mode.
