V.22bis/V.22/V.21/Bell 212A/103

Single-Chip Modem w/ Integrated Hybrid

SERIAL CONTROL INTERFACE MODE

The serial Command mode allows access to the

73K224BL control and status registers via a serial

control port. In this mode the AD0, AD1, and AD2

lines provide register addresses for data passed

through the AD7 (DATA) pin under control of the

RD and WR lines. A read operation is initiated

when the RD line is taken low. The next eight

cycles of EXCLK will then transfer out eight bits of

the selected address location LSB first. A write

takes place by shifting in eight bits of data LSB

first for eight consecutive cycles of EXCLK. WR is

then pulsed low and data transfer into the selected

DTMF GENERATOR

The DTMF generator controls the sending of the

sixteen standard DTMF tone pairs. The tone pair

sent is determined by selecting transmit DTMF (bit

D4) and the 4 DTMF bits (D0-D3) of the Tone

is gated by the transmit enable bit of CR0 (bit D1)

as with all other analog signals.
