3.3 Control Header

An eight pin header, JP3, provides reset, the #CONFIG signal, and a jumper

which dictates when used under Parallel C whether the ADM-C4X is to act as

a link engine, or as an attached processor:

GND 1 2 #CONFIG

GND 3 4 #RESET_IN

GND 5 6 #BUSRESET

MODE (see below) 7 8 MODE (see below)

3.3.1 #CONFIG (JP3pins 1 & 2)

#CONFIG is an active-low, open-drain output from the SMT401. If there is a

TIM fitted to the SMT401 #CONFIG can be driven low, but never driven high,

by the TIM.

Pin 1 is provided simply as an associated ground signal for #CONFIG.
