EVB configuration
Freescale Semiconductor 6
Note that by default these signals are not routed to the motherboard via the motherboard interface
connectors. However, zero ohm resistors may be installed at the reference designators listed in
Figure 2 if
the signals need to be routed to the motherboard for use as GPIO or other purposes.
Figure 2. Samtech ERF8 - MSC1 Connections (20-pin)
The following table lists the port and pins associated with each of the MSC channel signals.
4.5 ADC Channel Filters
For convenience, the EVB implements analog RC filters on one differential ADC channel pair, and two
single ended ADC channels. The single ended filter configuration is shown in
Figure 3 , and the differential
pair filter configuration is shown in Figure 4 . The user may modify these component values for the desired
application.
