Field Bit Description<br />
Trigger_Mode [12-15]<br />
[16-19] Reserved<br />
Trigger mode (Trigger_Mode_0..15): used to set the trigger mode to be used. For more<br />
information, see Asynchronous Triggering on page 34.<br />
Query the Trigger_Mode_Inq fields of the TRIGGER_INQ register for available trigger modes.<br />
Parameter [20-31] Parameter for trigger function, if required (optional)<br />
C.7 AE_ROI: 1A70 – 1A74h<br />
To calculate the base address for an offset CSR:<br />
1. Query the offset inquiry register.<br />
2. Multiple the value by 4. (The value is a 32-bit offset.)<br />
3. Remove the 0xF prefix from the result. (i.e., F70000h becomes 70000h)<br />
Format:<br />
