VI.2.1.4- Configuration Control Commands
ASEL
Select the Analog path option, like
Microphone input, Speaker attenuation.
Parametriccommand.
CONF
Configure.This commandconfiguresthe
modemenginefor datatransmissionand
handshakeprocedures (if any) in any of
the supported modes. The transmission
parametersare setto theirdefaultvalues
and can be modified with the MODC
command. Parametric command.
MODC
Modify Configuration. This command
allows modification of some of the
parameters which have been set up by
theCONF command.It can alsobe used
to alter the mode of operations (short
train). Parametric command.
DOSR
Define Optional Status Report. This
command allows the modification of the
optionalstatusreportlocatedinthestatus
area of the dual port RAM. One can thus
select a particular parameter to be
monitoredduring all modes of operation.
Parametriccommand.
DSIT
Define Status Interrupt. This command
allows the programming of the status
word bit that will generate an Interrupt to
thecontroller.Parametric command.
