CCITT V.23, V.21

Single-Chip

line. CR1 controls the interface between the

microprocessor and the 73K321L 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. All registers

are read/write except for DR which is read only.

Four 8-bit internal registers are accessible for control

and status monitoring. The registers are accessed in

read or write operations by addressing the A0 and

A1 address lines in Serial mode, or the AD0 and

AD1 lines in Parallel mode. The AD0 and AD1 lines

are latched by ALE. Register CR0 controls the

method by which data is transferred over the phone
