Transmit data input
TXDI is the modem
s
transmit data serial input. When configured for
serial data mode ( PDME bit is reset ) the modem accepts data bits
for transmission via this input. When transmitting data, the modem reads
the TXDI pin on the rising edge of DCLK. When the modem is con -
figured for parallel data mode ( PDME bit is set ), the TXDI pin is ig -
nored and transmit data is accepted by the modem via the DBFR register.
Pin No.

Description
Interrupt request
The modem can use IRQ to interrupt the host microprocessor
program execution. IRQ can be enabled in the modem interface
memory to be asserted in response to a specified change of
conditions in the modem status. IRQ is an open drain output
and must be connected to an external pull up resistor of suitable
value ( typically, a 5.6 K
, 1/4 watt, 5% resistor is adequate ).

Receive data output
RXDO is the modem receive data output.
Received data is output to the DTE via the RXDO pin in both
serial and parallel data modes ( PDME bit set or reset ).
When receiving data, the modem outputs a data bit on the falling
edge of DCLK.
The center of RXDO bits coincides with the rising edge of DCLK,
thus, the DTE should read RXDO on the rising edge of DCLK.
Request to send
When the RTS input is forced low, the transmitter starts transmitting
the modem training sequence according to the selected configuration.
Once the training sequence has been transmitted ( signaled by the
CTS pin and CTSB bit becoming active ), data present at either the
TXDI input pin in serial mode ( PDME bit is reset ) or written into the
DBFR register in parallel mode ( PDME bit is set ) is modulated and
transmitted.
The RTS input pin is logically ORed with the RTSB bit in the
interface memory.
