EMC2106 EVB User Manual
SMSC EMC2106 Revision 1.1 (08-22-07)
11
This EVB also allows for GPIO control and monitoring (see Table 3.4 ). Switches SW1 and SW2 allow
GPIO drive capabilites and LEDs provide visual confirmation of state change. .
The EMC2106 EVB also allows testing of all the muxed pins as well as voltage input adjustments for
the TRIP_SET and VIN4 functions.
Table 3.5 summarizes all of the jumpers that appear on page 2 of
the schematic SCH-7106.
