RM57L843: ADC1 Event Trigger Selection

Part Number: RM57L843

Hi,

I need to trigger my ADC from a PWM pin rising edge.

I have the following options as the trigger source per document SPNS215C page 165:

e_TPWM_B

e_TPWM_A1

ePWM_A2

ePWM_AB

My question is, what is e_TPWM_B, ePWM_AB and can I assume e_TPWM_A1 is just the ePWM_A1 output? (i.e. the 'T' does not mean anything special)

Thanks.

    Hi,

    Yes, e_TPWM_x is the same signal as ePWM_x. This is a typo correction (delete the 'T' from the signal name) that was missed from the datasheet update.

    These trigger options from the ePWM modules are described on page 168 through 170 of the same document.

    Thanks Sunil,

    The diagram on page 169 was exactly what I needed.

    Best Regards
