73K222BL

V.22, V.21, Bell 212A, Bell 103

Single-Chip Modem with Integrated Hybrid

Four 8-bit internal registers are accessible for

control and status monitoring. The registers are

accessed in read or write operations by

addressing AD0, AD1 and AD2 lines. 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 73K222BL internal state.

DR is the 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. Register control and status

bits are identified below:
