SEL186
I
Select Am186:
Identifies that a Am186
microcontroller board is connected and is
hosting the TIP board. This helps to
determine when the Ethernet controller
should respond to read and write cycles.
There is a 1-K
pulldown resistor
connected to this pin for when a Am186
board is not connected. SEL186 should be
driven High by any Am186 host boards
connecting to the TIP board.

FLASHWR
I
Flash Write Enable:
Write enable.
57, 59
VCC
I
Host Power:
+5 V DC provides power to
the comparator, which in turn provides
power to the MOSFET driver, which
drives the FETs, allowing the external
power supply to provide +5 V DC to the
board.
58
FLASHCS
Flash Chip Select:
Flash memory chip
enable.
60
EXTFLHCS
I
External Flash Chip Select:
An optional
external Flash memory chip select jumper.
The host boards can take advantage of
EXTFLHCS by making the TIP board’s
Flash memory select jumper the primary
Flash memory select component of the
two boards (theTIP board and the host
board). This minimizes components on
the host board.
