Advance Information
MT90812
65
The coefficient is an integer value from 0 to 255. If a single tone is desired then one of the registers is
programmed to zero. A tone output is disabled if both low and high coefficient registers are programmed to
zero.
Of the 7 programmable tone generators the first two can also be used to provide dual frequency squarewave
ringing signals. Tone Ringer enable bits, TRE1 and TRE2, in the TEDC register, enable the generation of the
squarewave ringing signals by the two Tone Ringer circuits. The Tone Generator and Tone Ringer functions are
described in Section 16.0

Conference Party Control Register (CPC1-15)
The
Conference Party Control
register contains the conference ID, start bit, insertion tone enable and
outgoing channel attenuation.
The register is configured as follows:
The conference block provides conference call capability in the MT90812 and supports a total of 15 parties
maximum, distributed over up to 5 conferences, i.e. 1x15 parties, 3x5 parties, 5x3 parties etc. Each of the 15
parties are associated to a conference by programming the corresponding Conference ID number.
As a party is added to a conference, if the insertion tone bit (IT) is set, all channels connected in a conference
will have the tone added to the conference output. The DM address of the desired tone must be programmed at
location 6F
H
of CML, (16F
H
non-mux mode, EF
H
for mux-mode addressing). The PCM data from the specified
Data Memory location will be added to the conference output for a specified tone duration.
Read/Write Address is: 30-3EH
Reset Value is: 00

Start Conference Setting
. The
ST
bit for the
first
party programmed for a
conference will remove any other parties that may have been previously
programmed for that conference. This is implemented at the time the Conference
Party Control Register is updated and the state of the ST bit is not actually stored in
the register.
