What is the maximum number of usable analog inputs when using the 21469 EZ-Kit Lite, which has 4 analog inputs, and the EZ Extender board, which has 12 analog inputs? It appears that the AD1939 on the EZ-Kit and the first AD1939 on the EZ Extender are both connected to SPORT01. Correct? So does that mean that I am limited to 12 analog inputs? Or is there any way to get all 16 analog inputs functional?
