Muting of audio circuits when received signal levels fall below a pre-
determined value.
Static-RAM chip used for volatile, program/data memory.
Synchronous Serial Interface on the DSP56001 consisting of six signals and
used for an RX and TX modulated data interface to the ADSIC.
An operating mode whereby the radio is muted but still continues to monitor
data.
