CCS/TIDM-SOLAR-DCDC: 3p3z coefficients in dplip.pdf and CONTL_3P3Z.asm

Hello!  I try to implement 3p3z in my project.  3p3z has 7 coefficients and  3 bounds.

But  I read in dplib.pdf that :

CNTL_3P3Z_Coef1 = &CNTL_3P3Z_CoefStruct1.b2;  WHy b2,  If brim of structure is  CNTL_3P3Z_CoefStruct1.b3 ?

And in CONTL_3P3Z.asm:

_CNTL_3P3Z_Coef:n:    .usect     "CNTL_3P3Z_Section",2,1,1        ; coefficients & saturation limits (14 words)


Why 14 words , if 7 coefficients and 3 bounds = 20 words?

Please explain what to do.

    Hello Michael,

    Thank you for pointing out these mistakes.  I can see the first one has been corrected in the documentation for the most recent library releases.

    The second one is still in the documentation.  The coefficient structure is indeed 20 words, which is what the comment should say.  I think the author put the data buffer size in the wrong comment line.

    We will note this for correction in the next revision.

    Regards,

    Richard
