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 A0, A1 and
A2 address lines in serial mode, or the AD0, AD1 and
AD2 lines in parallel mode. The address lines are
latched by ALE. Register CR0 controls the method by
which data is transferred over the phone line. CR1
controls the interface between the microprocessor and
the 73K224L 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:
