USB Port

The USB type-B connector allows a USB connection to a PC. The power pin of the connector

goes to a jumper (J5) labeled “VBUS PWR” to allow USB power to be disconnected from the

system for emulator based development. In addition the USB signals can be viewed with an

oscilloscope or logic analyzer at header J7. For best USB signal quality, remove the jumpers

on J8 and J9 that connect the PS/2 port.

PS/2 Port

The PS/2 connector allows a PS/2 connection to a PC using the supplied cable. The power

pin of the connector goes to a jumper (J13) labeled “PS/2 PWR” to allow PS/2 power to be

disconnected from the system for emulator based development. In addition the PS/2 signals

can be viewed with an oscilloscope or logic analyzer at header J7. The enCoRe II pins used

for PS/2 are normally P1.0 and P1.1, but the alternate pins P1.5 and P1.6 can be used by

moving the jumpers on J8 and J9 to the side labeled “ALT PS/2”.

Analyzer Headers

P1, P2, and P3 are 20-pin headers that are compatible with Agilent logic analyzer terminator

adapters. This feature allows for a quick and simple debugging connection.

Prototyping Area

An area on the board is available for user-customized prototyping. The through-hole area

contains 0.1” spaced holes appropriate for DIP devices. On each side of the through-hole area

there is a ground row and a power row. Each power row can be individually configured to use

either the board’s VCC or the VREG output from the enCoRe II. There is also a surface mount

prototype area that accepts either 0.050” pitch parts or 0.025” pitch parts. Holes on the

outside of the surface mount pads allow signals to easily be soldered from elsewhere on the

board. A single row of signals above the proto area allows enCoRe II signals to be wired to

the proto area. This row has all signal names in silkscreen by their respective holes on both

the top and bottom side of the board.
