Question about VCOFRQ setting in S12ZVL

Hello all,

 

I am currently at the configuration of the fvco of the S12ZVL128. However, I find some difference in the datasheet for VCOFRQ setting. Just want to confirm which is correct. 

 

In page. 235, chapter '9.3.2.4 S12CPMU_UHV Synthesizer Register (CPMUSYNR)', I found the following information:

However, in page. 285, for the ‘9.7.3 Application Information for PLL and Oscillator Startup’, it says that range is between 48MHz to 80MHz for VCOFRQ[1:0] = 01:

 

 

I have also seen the same information in my register window when I was debugging:

 

 

Could anyone confirm which is the correct range for the setting?

 

Thank you,

 

Junxi
