REGISTER DESCRIPTIONS
Eight 8-bit internal registers are accessible for
control and status monitoring. The registers are
accessed in read or write operations by addressing
the AD0, AD1 and AD2 lines in serial mode, or in
parallel mode. The address lines and
CS
are latched
by ALE in the parallel mode. Register CR0 controls
the method by which data is transferred over the
phone line. CR1 controls the interface between the
microprocessor and the 73K324BL internal state.
DR is a detect register which provides an indication
of monitored modem status conditions. TR, the tone
control register, controls the DTMF generator,
answer and guard tones and RXD output gate used
in the modem initial connect sequence. CR2 is the
primary DSP control interface and CR3 controls
transmit attenuation and receive gain adjustments.
All registers are read/write except for DR and ID
which are read only. Register control and status bits
are identified below:
