TMS570LC4357: Error in TRM for description on PLLCTL1/PLLMUL

Part Number: TMS570LC4357


Hi,

There seems to be a minor error in the TMS570LC43x Technical Reference Manual (SPNU563 / May 2014) section 2.5.1.25 PLL Control Register 1 (PLLCTL1)

For the PLLMUL field (15-0), the description states that:

> NF = (PLLMUL / 256) + 1, valid multiplication factors are from 1 to 256.
> f VCO CLK= f INT CLK x NF

And then provides the (erroneous) example value:

> 100h >> f VCO CLK= f INT CLK x 1

It should be:

> 0h >> f VCO CLK= f INT CLK x 1
> 100h >> f VCO CLK= f INT CLK x 2

Regards,

Bastien

  • Thanks Bastien.

    I will forward your find to our documentation department for consideration in a future update. Also note that there is a link in the document for direct feedback to the documentation team that you could use for this type of finding in the future.
