Supporting chipsets (voice-
enabled devices only):
• MDM8200A (min f/w rev:
R0.2.15.0)
Note: This command is not
password protected.
Read a codec register
(This command is used only when the modem is controlling a codec in commercial
mode—[AT!AVUSEMCU=0 and AT!AVMODESET=1].)
This command is used to read the value stored in a codec register.
Usage:
• Execution: AT!AVCODECRED=<register address>
Response:
!AVCODECRED: <value>
OK
Purpose: Return the <value> stored in the specified register.
• Query list: AT!AVCODECRED=?
Purpose: Return the command format and supported <values>.
Parameters:
<register address> (Address of register)
• Valid range: 0–0xFFFF
<value> (Value that is stored in the specified register)
• Valid range: 0–0xFFFF
!AVCODECRST
Supporting chipsets (voice-
enabled devices only):
• MDM8200A (min f/w rev:
R0.2.15.0)
Note: This command is not
password protected.
Configure codec registers for reset
(This command is used only when the modem is controlling a codec in commercial
mode—[AT!AVUSEMCU=0 and AT!AVMODESET=1].)
This command is used to populate a table with up to four (4) register values that the
modem will access when AT!RESET is issued. These values are used to stop the
codec before the modem resets.
Important: If this command is not used to populate the register reset table, the
modem will receive I2S signals when it resets and will go into an abnormal
(undefined) state.
Note: AT!AVCODECRST=0xFFFF,0xFFFF is not allowed.
Usage:
• Execution: AT!AVCODECRST=<register address>,<value>
Response:
OK
Purpose: Set the specified register to the <value>.
• Query list: AT!AVCODECRST=?
Purpose: Return the command format and supported <values>.
Parameters:
<register address> (Address of register)
• Valid range: 0–0xFFFF
• 0xFFFF is used to set the delay
<value> (Value to store in the specified register)
• Valid range: 0–0xFFFF
• 0xFFFF is not valid when <register_address> = 0xFFFF. (This combination
identifies the end of the configuration table.)
