Programming Examples
Some examples of the programming steps required
to set-up various telephony functions are given. Note
that these steps are from the power-up reset default
definition. If some other state is currently true then
some programming steps may be omitted while new
ones may be required.
Initialization
Description
Address
DATA
choose ST-BUS vs SSI
(ie ST-BUS with C&D channels enabled)
or (ie SSI at 256kHz BCL)
10h
10h
70h
05h
power up oscillator and FDI
same as above with B2 channel for ST-BUS
0Eh
0Eh
00h (other bits as required)
04h (other bits as required)
A-Law vs
μ
-Law as required
(ie CCITT
μ
-Law and gains low)
or (ie CCITT A-Law and gains increased)
0Fh
0Fh
00h (default value so no write required)
2Ch
Standard Full-duplex handset call
Description
Address
DATA
program Initialization steps above
set sidetone gain (ie 0 dB)
set gain (ie Rx = +3 dB, Tx = 0 dB)
0Bh
19h
04h (leave speaker gain defaulted to 0dB)
89h (or as required, defaults = 0dB)
select transmit path
(ie handset mic to B2 for ST-BUS)
or (ie handset mic for SSI)
12h
12h
09h
01h
select receive path
(ie handset speaker to Rx filter plus
sidetone)
or (as above plus receive to AUXout also)
13h
13h
81h (for standard headset only)
91h
optional:
set Filter/CODEC Rx and Tx gain
0Ah
as required (0dB default)
Group Listening
Description
Address
DATA
program Initialization steps above
set gain (ie Rx = +3 dB, Tx = 0 dB)
19h
89h (or as required, defaults = 0dB)
set sidetone gain (ie 0 dB) and also
set handsfree speaker gain independent
of the rest of the receive path (ie 12dB)
0Bh
94h
set high threshold level
set low threshold level
1Dh
1Eh
as required or leave default value
as required or leave default value
enable group listening with 12dB of atten.
1Ch
A4h
select transmit path
(ie handset mic to B2 for ST-BUS)
or (ie handset mic for SSI)
12h
12h
09h
01h
select receive path
(ie Rx filter to both handset and
handsfree speakers with sidetone)
13h
85h
