TMS570LC4357: Confused about N2HET priority level naming scheme

hongbo Yang

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

In tms570lc4357 datasheet P118-, the N2HET1 has high level interrupt ( priority level = 1) and low level interrupt (priority level = 2)

but N2HET2 has Level 0 and Level 1.

In 23.4.10 Interrupt Priority Register (HETPRY)

it shows interrupt priority with level 1 and level 2

are these related ? why N2HET2 and N2HET1 have different level x?

Thanks

Hi Hongbo,

Actually, it was a typo mistake for N2HET2.

It is not Level 0 and Level 1, it should also be Level 1 and Level 2 respectively.

Basically, in each instance of N2HET the interrupts can be configured in two levels they are Level 1 and Level 2, they can also called as High priority level interrupt and Low priority level interrupt respectively.

Thanks for pointing out this document error and we will correct this typo in next release of document.

Thanks & regards,
Jagadish.

Thanks, and the text should also be changed in HalCoGen.
