3.3
The most currently used ARCOFI-operating modes are documented in the following
table. The 12 ARCOFI-configuration registers have enough build-in flexibility to
accommodate an extensive set of user calling procedures.
The following operating mode description table is not exhaustive but should be used as
an example of possible functions performed by the ARCOFI.

Operating Modes
Description
Power-on reset: when power is supplied to the ARCOFI an
internal power-on reset is generated. In addition a hardware reset
via an RC-network connected to input pin RS will force all
ARCOFI internal registers to default values. The
ARCOFI-registers reset state is described in section 3.1 and 4.
The system microprocessor can initialize the ARCOFI via the
IOM-2 or the SCI-bus with a different set of filter and
configuration values. Whilst remaining in power-down
(GCR.PU = 0) a new set of filter coefficients and configuration
bits can be loaded in the ARCOFI.
The system MPU detects activity from the hookswitch or from the
keyboard. The ARCOFI can be placed in HANDSET state where
all handset l/O are enabled (AMI & AHO activated).
The system MPU detects an incoming call, the ARCOFI can be
placed in a RINGING state by activating the tone ringer via
TGCR/TGSR and configuring the ARCOFI such that either the
LSP/LSN-output or the piezo output (pins PZ1/PZ2) are enabled.
An emergency ringing is also implemented. In this mode, only the
tone ringer and the loudspeaker amplifier are active (AMI- and
AHO-amplifier are disabled by the user). The tone ringer signal is
directly switched to the loudspeaker amplifier ALS.
All audio inputs can be disabled by forcing the AMI-amplifier
(ATCR) to power-down. DTMF tones are generated with the tone
generator and are output to the transmit path.
Handset audio path can be enabled by forcing a HANDSET
mode. A single tone can be superimposed into the audio receive
path so as to provide audible feedback when dialling.
The handset l/O and the loudspeaker outputs LSP/LSN are
active (ATCR & ARCR).
