When high, the new call tone generator output from the DSP is selected as the source for the loudspeaker path. When low, the
Active high reset. Performs the same function as PWRST but does not affect the microport or the watchdog circuits. To remove
this reset a PWRST must occur or this bit must be written low.
When high, the microport transmit and receive are performed on separate pins. DATA1 is receive while DATA2 is transmit.
When low, the microport conforms to Intel MCS-51 mode 0 specifications; DATA1 is a bi-directional (transmit/receive) serial
data pin while DATA2 is internally disconnected and tri-stated.
When high, A-Law (de)coding is selected. When low,
When high, sign-magnitude bit coding is selected, When low, true CCITT PCM coding is selected.
When high, the receiver driver nominal gain is set at -9.7 dB. When low this driver nominal gain is set at -12.3 dB.
When high, the transmit amplifier nominal gain is set at 15.4 dB. When low this amplifier nominal gain is set at 6.1 dB.
When high, the side-tone nominal gain is set at -18.8 dB. When low this nominal gain is set at -11 dB.
CODEC output is selected for the loudspeaker path. Note that SPKR EN must also be set high for new call tone to function.
