Part Number: TMS320F28035

Hi experts,

What is the minimum pulse width for trip zone input?

DS(SPRS584M) description is 2*TBCLK but TRM(SPRUI10) description is 3*TBCLK.

Sasaki-San,

Please use 3 TBCLK periods. This will ensure the data is latched into the CBC and OSHT trip mechanisms. If the pulse is shorter than this then the PWM trip may not behave as expected.

I have started the process to correct the documentation.

Thank you,
Cody Watkins
