STATUS Indicators
The EVB board provides 5 Ethernet status indicators, TX_RX, LNK, 100, DUP, and COL, that
are controlled by NE64 port PTL0 – 4 outputs respectfully. CONFIG switch position 6 must be
ON to enable these indicators on the EVB board. Ethernet status indicator operation is
provided by NE64 PHY control or the user may apply under application software control of the
individual PTL ports. Active port level is logic 0 or 0V.
COM Ports
The EVB9S12NE64 provides two RS232 type COM1 / 2 ports or a RS232 COM1 port and an
IRDA type communication port. COM1 or COM2 may be optioned with flow controls with the
FLOW_SEL options.
connections in hardware. User must apply correct software operation to the associated SCI
port for the communication type selected.
COM_Switch
The COM_SW provides NE64 I/O port to communication peripheral connections on the
evaluation board. This allows the user to apply the provided communication transceivers and
ports, or to apply the associated I/O to other purposes. The switch positions and FLOW_SEL
options should be reviewed first if any operational problems are encountered with the COM1,
COM2, or IRDA ports.
