AM2432: How to configure EHRPWM_TZn_IN0

Tool/software:

Hello,

this question is a follow-up to my post "AM2432: Use (general) ECAPs to generate a clock signal for delta-sigma". I came back on this topic as I wanted to configure the Trip Zone TZn_IN0 (GPMC0_AD2/T19) via syscfg for the EPWM. However i cannot find this option/pin in the EPWM section. (The PWM0_TZ_OUT (PRG0_PRU0_GPO19/G2) for PRU ICSS PWM is/can be configured in syscfg). Did i miss something?

Thanks in advance,

Christian

Hi Christian, unfortunately we don't have Trip Zone options enabled in AM243x EPWM's Sysconfig module, this is something users need to manually configure

thank you,

Paula

Hi Paula,

thanks for your response. Is there any particular reason for this? (Since TZn_IN belongs to the EPWM module, i would expect to be ablle to configure this via syscfg). However, since it is not possible, can you show / explain how to configure it manually?

Thanks in advance,

Christian
