5.4.15 HRDLSetAnalogInChannel
Copyright © 2005-2010 Pico Technology Ltd. All rights reserved.
This function enables or disables the selected analog channel. If you wish to enable
an odd-numbered channel in differential mode, you must first make sure that its
corresponding even-numbered channel is disabled. (For example, to set channel 1 to
differential mode, first ensure that channel 2 is disabled.)
