status has been updated by the D6571E, has not been read by Host
0:
status does not contain information that has not been read by Host
The status will be updated by the D6571E each 1/2 of a frame (16.5 ms for 7.2 kHz sampling rate and 15 ms for 8 kHz
sampling rate). The NEW bit will be set each time when the D6571E updates status. The New bit will be reset each time
when Host reads Line Status.
