Notes
Channel Interface Selection Pins : Use these bits to select the channel
interface type (parallel, serial, active, passive) according to Table 3-A.
See full description in section 3.2.
A/D-D/A Select Pins :
compatible with the A/D-D/A chip in the design, then simply use Table
5-A to select the interface.
described in section 4.1.14.4 should be used to configure this interface.
Coding Rate Select Pins : Use these bits to select the voice and FEC
rates according to Table 6-A. See full description in section 6.2. The
coding rates are also selectable using the Command Frame interface
described in section 4.1.14.2.
Voice Activation Detection Enable Pin. Active HIGH. See Section 6.4.
VAD can also be enabled/disabled using the Command Frame interface
as described in section 4.1.14.4.
Echo Canceller Enable Pin. Active HIGH. See Section 6.3. The Echo
Canceller can also be enabled/disabled using the Command Frame
interface as described in section 4.1.14.4.
Standard Sleep Enable Pin. Active HIGH. See Section 6.6.1.
Slip Control Enable Pin. Active HIGH. See Section 6.7.
Clock Input 1. 26-30Mhz input. See Section 7.4
Clock Input 2. See Section 7.4
Buffered Clock Output. See Section 7.3
AMBE-1000 Reset pin. Active LOW. See Section 7.3
Hardware Sleep pin. Active LOW. See Section 6.6.3.
Encode Packet Ready : During normal operation this active LOW signal
will go low once every 20 milliseconds to notify the controller that the
encoder has a coded frame to output. See section 3 for further details.
Decoder Packet Empty : During normal operation this active LOW signal
will go low once every 20 milliseconds (see exception section 4.1.14.6)
to signify that the decoder is ready for another frame of data to be
input. See section 3 for further details.
Parallel Interface : Data 7 ; MSB
Serial Interface : Unused I/O, see note 1. Ground through 10kOhm.
Parallel Interface : Data 6
Serial Interface : Unused I/O, see note 1. Ground through 10kOhm.
Parallel Interface : Data 5
