3.2.2 DataRAM
Address: ME 0x000000
The DataRAM is a memory area of 65536 16-bit locations, mapped within the IP
memory space.
3.2.3 Channel
List
Address: ME 0x020000
The Channel List is a memory area of 64 12-bit locations, mapped within the IP
memory space. It allows for the setup of calibration, gain and differential / single
ended mode selection on a per channel basis.

SE/DIFF Single-Ended/Differential mode selection
This bit select whether the channels are in single ended or differential mode. If the bit
is set to 0, then the channels are in single-ended mode and when the bits are set to 1
the channels are in differential mode.
Threshold high
Allow interrupts in relation with the “Threshold High” value. See Table 2.2.2 for bit
selection.
Threshold low
Allow interrupts in relation with the “Threshold High” value. See Table 2.2.2 for bit
selection.
