We have some doubts on ADC modules in MPC565.
It consists of 40 channel and two ADC modules viz QADC A and B. We are
developing low level driver for this module in C.
In reference manual Chapter 13, QADC is described as follows
The two queued analog-to-digital converter (QADC) modules on the MPC565
are 10-bit, unipolar, successive approximation converters with analog
multiplexers. These modules are configured so each module can access
all 40 of the part's analog inputs.
What is the need for having two modules separately with access to same
channels?
When we are writing drivers we are not sure how to use both the modules.
Please advice.
