AMBE-3000F™ Vocoder Chip Users Manual
Version 3.4, April, 2014
Dat
a and Configuration Packets
If m
ode is 0 then parity fields will be disabled for all output packets beginning with the response to this packet. The AMBE-
3000F™ 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-
3000F™ 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.
PKT_PARITYMODE Response field (2 bytes) this field indicates that the PKT_PARITYMODE field in the corresponding
control packet was received without error.
