MC56F84789 missing PWMB registers definitions in MC56F84789_rev1.0.h

The Reference Manual for the MC56F847xx family states that PWMB has the registers: PWMB_SMnFRACVALx and the PWMB_SMnFRCTRL (pages 744-751).

They were included in the last revision as stated on page 1097 (A.28 PWMB changes).

The processor header file (...\CW MCU v10.6\MCU\lib\wizard_data\DSC\DataBase\derivatives\include\MC56F84789_rev1.0.h), however, do not include them, and it has to be done by hand.

Does the processor really have the fractional registers for PWMB?

 

page 1097 (A.28 PWMB changes) also states that:

"In Introduction section, reworded to clearly indicate that PWMB supports digital dithering, while PWMA does not

support digital dithering."

 

However, in page 743, the introduction says the opposite:

The primary difference between PWMB and PWMA: PWMA supports NanoEdge placement (digital dithering); PWMB does not support NanoEdge placement (digital dithering).

 

I suppose that page 743 is correct, as the rest of the document support its version. Am I correct?

 

 

Thanks for the attention.
