-law/A-law PCM Data Pump:
The Host sends the command word (which contains data) to the D6571E. The D6571E echoes the received data in the
status word (Data Transfer status).
Data Transfer Command:
(DC1 . . . DC_120)
DATA WORD
(15 - 0)
Data Transfer Status:
(DS1 . . . DS_120)
ECHO OF DATA WORD
(15 - 0)
For both TrueSpeech and
μ
-law/A-law PCM data pumps, in each frame the Host issues command C2, reads status S2,
then issues command C3. The actual data transfer starts after S3 is received by the Host. After data transfer is completed
the Host should issue the next C2 command. The D6571E checks bits 15 -12 in each C2 and C3 command for the correct
code. If an incorrect code is detected, the D6571E will return to Idle mode.
NOTE:
Instead of sending the Data Pump C2 command shown above, the Host can send a Set Volume Level command to
set the volume level. The D6571E will respond with status S2 of Data Pump mode. The ‘Set Volume C2 Command’ and
status S2 are shown below.
Command (C2): Set Volume
1 1 0 0
1 0 0 0
1 0 0
VOLUME
(15 -12) (11 - 8) (7 - 5) (4 - 0)
For the appropriate VOLUME level settings, please refer to the Set Volume Level command of the Self Test and
Initialization mode (Test Mode = 1000).
Status (S2): Set Volume
1 1 0 0
0 0 0 0 0 0
