Description
I Test pin 4
O Modem Control Output, for external modem:
Memory address mapping of the controller is
E800H.
I Receive Data Rate Clock:(External)
This pin is used as reference clock of DSPRXD pin.
I 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.
I Transmit Data Rate Clock:(External)
This pin is used as reference clock of DSPTXD pin.
I Modem Transmit Data (External)
Shifted into DM6581/DM6582 from EIA port
through this pin at the rising edge of TXDCLK.
I 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.
P Ground
O Modem Control Output
For external modem, these pins are bit7~4 of the
modem control output. Memory address mapping
of the controller is C800H.
I Modem Control Input
For external modem, these pins are bit3~0 of the
modem control input. Memory address mapping of
the controller is C800H.
P +3.3V Power Supply
I Test pin 2,normal ground
I Test pin 3,normal ground
I Reset:
An active high signal used to reset the DM6588.
I Crystal Oscillator Input
O Crystal Oscillator Output
O Controller Program Write Enable:
This pin is used to enable FLASH ROM
programming.
O Data Output Pin Of Serial Port 1
The serial data is clocked out through this pin
