Modem Control Output
, for external modem:
Memory address mapping of the controller is
E800H.
Receive Data Rate Clock:(External)
This pin is used as reference clock of DSPRXD pin.
Data Input Pin Of The Serial Port 2 (External)
The serial data is sampled at the falling edge of the
SCLK. The MSB is coming immediately after the
falling of FR_SP2 signal.
Transmit Data Rate Clock:(External)
This pin is used as reference clock of DSPTXD pin.
Modem Transmit Data (External)
Shifted into DM6581/DM6582 from EIA port
through this pin at the rising edge of TXDCLK.
Data Input Pin Of The Serial Port 1 (External)
The serial data is sampled at the falling edge of the
SCLK. The MSB is coming immediately after the
falling of FR_SP1 signal.
