The yellow ETH ON LED indicates that the Ethernet port transceiver, Davicom DM9161E, is active.
3•2•16
The yellow RS232 Port 1 ON LED signifies that the RS232 transceiver, connected to SCC3, is active and that com-
munication via that medium is allowed. The RS232 transceiver is in shutdown mode when unlit - an indication that
the associated MPC pins may be used off-board via the expansion connectors.
3•2•17
The yellow FAST ETH ON LED indicates that the Fast Ethernet port transceiver, Davicom DM9161E, is active. The
Davicom outputs pins are in tri-states when unlit - an indication that the associated Port D pins may be used off-board
via the expansion connectors.

The yellow RS232 Port 1 ON LED signifies that the RS232 transceiver, connected to SMC1, is active and that com-
munication via that medium is allowed. The RS232 transceiver is in shutdown mode when unlit - an indication that
the associated MPC pins may be used off-board via the expansion connectors.
3•2•19
The yellow PCMCIA ON LED indicates the following:
When unlit it indicates that the above noted buffers are tri-stated and that the pins associated with the PCMCIA
channel A may be used off-board via the expansion connectors.
3•2•20
The yellow FLASH ON LED indicates that the FLASH SIMM has been enabled in the BCSR1 register. For example,
accessing the CS0~ address space will hit the Flash memory. When unlit the Flash has been disabled.
3•2•21
The yellow DRAM ON LED indicates that the DRAM SIMM has been enabled in BCSR1 and that accessing CS2~
(or CS3~) will hit on the DRAM. When unlit the DRAM has been disabled in BCSR1.
3•2•22
The green SGLAMP LED indicates that this signal is active (low). When inactive there is no LED light. The LED is
used for software signalling. Controlling the led is done via BCSR4[3].

Address & strobe buffers are driven towards the PCMCIA card.
Data buffers are driven to / from the PCMCIA card whenever CE1A~ or CE2A~ signals are asserted.
Card status lines are driven towards the MPC from the PCMCIA card.
