Jumpers 2-5 Getting Started 2.2.3 Channel 0 Analog Output With a one-channel DAC installed, this signal is the primary analog output(output A). With a two-channel DAC installed, the pinout of these devices effectivelyresolves this channel to be the secondary analog output (output B). Analog Input Co...

Page 15 - Switches; There are three switches present on the EVM:

Switches 2-6 2.2.7 Clock/Timer Routing A variety of options are available to the user. Be careful about altering these. Clock/Timer Routing Reference Designator Functional Description W21 This jumper defines the clock that the ADC and DAC use for all their timing. The user can selecteither the outpu...
