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 EMC2104/05 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.
