TMS570LS3137 ADC trigger via RTI Compare 0

Charles Johnston

Hello,

When configuring an ADC to trigger off of RTI_COMP0, does the rising / falling edge setting have any effect? For example, if set to falling edge, will the trigger occur when the corresponding RTIINT flag is cleared?

Thanks, Charlie Johnston

Hello Charlie,

That is correct. By default the trigger event is a falling edge, so for an RTI compare0 interrupt the trigger will happen when the flag is cleared. You can also refer to the post:

http://e2e.ti.com/support/microcontrollers/hercules/f/312/p/287063/1003111.aspx#1003111

This includes information that allows you to automatically clear the RTI interrupt flag without actually interrupting the CPU. This information has been recently included in our documentation (SPNU499).
