I just compiled a dummy project for your chip, with the clock selected
as you are doing, and the changes made to the processor file. It shows
it setting PLLFBD to 0x32, and CLKDIV to 3. So input divided by 5 to give
5MHz into the PLL, and then * 52 to give 260MHz out of the VCO. Then
divided by 2.
If you are not seeing these in the .LST file, you are not doing the changes
to the processor file (or to the include of this) correctly. Remember you
have to recompile after the changes.

I am grateful for your test.

How did you find the PLLFBD & CLKDIV & VCO is divided by 2? Could you please copy here relevant assembly section?

Here is 'main' from my *.lst file:

Here is a tip. Post your .LST file segment in Symbolic mode.
It's easier to understand and interpret code when in that mode.

Here are instructions from Ttelmah showing how to change the compiler
(when using the CCS IDE) to use Symbolic mode:

Options
Project
Output Files

Then in the column 'List File', tick the box 'Symbolic' and apply.

Then re-compile and re-post your code.

In non symbolic mode you just need to look for the addresses. So:
Code:

//This is the bit doing the clock settings.

00800: MOV #32,W4 //50 into W4
00802: MOV W4,746 //Now 50 into the PLLFBD register
00804: MOV #3,W4 //now 3 into W4
00806: MOV W4,744 //into the CLKDIV register
00808: DISI #E
0080A: MOV #103,W0
0080C: MOV #743,W1
0080E: MOV #78,W2
00810: MOV #9A,W3
00812: MOV.B W2L,[W1]
00814: MOV.B W3L,[W1]


The data sheet tells you the addresses for all the registers.

I got the disassembly code and looks the same (compared the content):

Did you 'Apply'.
Needs to happen.

With symbolic mode selected, the compiler will put register names in
to replace the addresses.

I tried to do the same with 2 different PCs:


I clicked on 'apply' then cleared output files and built all again.
But nothing has been changed in the *.lst file.

Maybe I need to check something else?

While I don't use it...
..from your screenshot...
...maybe try checking 'SFR NAMES' in the 'List File' box ??
