If mode is 0 then parity fields will be disabled for all output packets beginning with the response to this packet. The AMBE-

3000™ Vocoder Chip will not require a valid parity byte for future received packets.

If mode is 1 then parity fields will be enabled for all output packets beginning with the response to this packet. The AMBE-

3000™ Vocoder Chip will reject all future received packets that do not have a valid parity field.

All other values for mode are reserved and should not be used.
