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

Bastien
