TMS570LS3137: Error in TMS570LS3137 TRM in relation to open drain on I2C?

Part Number: TMS570LS3137
Other Parts Discussed in Thread: HALCOGEN

Hi,

I have found an apparent discrepancy between HalCoGen and the TRM for the TMS570LS3137 in the section on I2C.

When you hover your cursor over the open drain check box a pop up appears that says "Enable open drain output", which I take to mean that if you check the box it is enabled. The resultant code puts a 1 in the PDR register. However, when you look at the TRM (spnu499C - March 2018, page 1606) it says 1- open drain function is disabled.

Which is correct, HalCoGen or the TRM?

Regards

Andy
