Bits 31:24 Reserved, must be kept at reset value.
Bits 23:0 Gx_IOy: Gx_IOy channel mode
These bits are set and cleared by software to configure the Gx_IOy as a channel I/O.
0: Gx_IOy unused
1: Gx_IOy used as channel
Note: These bits must not be modified when an acquisition is on-going.

These bits are set by hardware when the acquisition on the corresponding enabled analog
I/O group x is complete. They are cleared by hardware when a new acquisition is started.
0: Acquisition on analog I/O group x is on-going or not started
1: Acquisition on analog I/O group x is complete
groups are not set.
