am335x trm error: ehrpwm, tbctl register

Vasileios Tsounis

Hello,

I would like to point out an error in the trm. I'm referring to the latest version; as of december 2013, "sprugh73j.pdf". Looking at the TBCTL register description on pages 2071~2072:

TBCLK = SYSCLK/(HSPCLKDIV - CLKDIV)

This is wrong, testing using direct register acces in CCSv5.4, on the BeagleBone (r6), shows that in fact the correct formula should be:

TBCLK = SYSCLK/(HSPCLKDIV * CLKDIV) or TBCLK = SYSCLK/(HSPCLKDIV x CLKDIV),

i.e. the product of the dividers is the total sysclock prescaler.

Best regards.

Hi Vassilis,

Thanks for finding this. The correct way to report TRM errors is to use the "Submit Documentation Feedback" link, which can be found at the bottom of each page of the PDF document. This will lead you to a simple web page, where you can describe the issue and it will be sent directly to the TRM team.
