PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
All three conversion groups can be configured for event-triggered operation, providing up to three event triggered groups.
The trigger source and polarity can be selected individually for group 1, group 2 and the event group from the options identified in the first table following for MibADC1 and in the second table following for MibADC2.
Event # | SOURCE SELECT BITS for G1, G2 or EVENT (G1SRC[2:0], G2SRC[2:0] or EVSRC[2:0]) | Hookup |

NOTE
The Trigger is present, even if the pin is not available.
The application can generate the trigger condition using these signals by configuring the corresponding device pins as input pins and driving them from an external source, or by configuring them as output pins and driving them by software. The pin doesn't have to be present on the package to be able to be used as a trigger.
The interrupt request signals (RTI compare 0) are driven HIGH when the interrupt condition occurs. So if the ADC is required to be triggered on the interrupt being asserted, select the rising edge for this trigger source. The ADC can be still triggered using the falling edge on the interrupt line. In this case, the falling edge occurs when the interrupt line is deasserted.
