VOICE CODEC
and a 14-bit D/A converter with integrated filtering. It supports
several different clocking modes. The voice codec is supplied
by V
The analog is using the REFC bias and the half rail bias at
REFA.

A/D CONVERTERS
converters which convert the incoming analog audio signals
coming from the microphone amplifiers into 14-bit linear PCM
words at a rate of 8.0 kHz or 16 kHz. Following the A/D
conversion, the audio signal is digitally band pass filtered.
The A/D is enabled by setting the VCEADCEN bit. The
sampling rate is set by the VCE8K16K bit.
