RS-232 Port Signal Description
In the list below, the directions ’I’, ’O’, and ’I/O’ are relative to the M68360QUADS-040 board. (I.E. ’I’ means
input to the M68360QUADS-040)
CD ( O ) - Data Carrier Detect. This line is always asserted by the ADS.
TX ( O ) - Transmit Data.
RX ( I ) - Receive Data.
DTR ( I ) - Data Terminal Ready. This signal is used by the software in the ADS to detect if a
terminal is connected to the ADS board.
DSR ( O ) - Data Set Ready. This line is always asserted by the ADS.
RTS ( I ) - Request To Send. This line is not connected in the ADS.
CTS ( O ) - Clear To Send. This line is always asserted by the ADS.
4.11.5
M68360QUADS-040 Status Register
The status register is a 16 bit wide READ ONLY register used to hold board status, level 7 interrupt source
identification and an input register for ADI interface signals.

Status Register Bits Description
DTR* - When active ’0’, indicates that a terminal is connected to the serial port.
H_NMI* - When active ’0’, indicates that the last level 7 interrupt (NMI) was generated from the
host via the ADI port.
INACK - When active ’0’, indicates that a Host Interrupt Acknowledge cycle is in progress.
ADSSEL - When active ’1’, indicates that the board is selected by the ADI port.
HSREQ* - When active ’0’, indicates that the host request to write a data byte to the board via the
ADI port.
HSACK* - When active ’0’, indicates that the host has successfully read a byte of data written to
it by the board via the ADI port.
HSTEN - When active ’1’, indicates that the board is connected to an ADI port.
HSVCC* - When active ’0’, indicates that the host computer is alive (not turned off).
