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
register occurs on the rising edge of WR.
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
Register. Transmission of DTMF tones from TXA
is gated by the transmit enable bit of CR0 (bit D1)
as with all other analog signals.
