Hi,

here is just a question for interest.
My program uses five PCA modules and has five software blocks which work at same way - they use different variables` locations but do exactly same things each at own PCA module. So to reduce code space I made only one subroutine which accepts DPTR as a pointer to the look-up table of one of those blocks. All things are good but... Due some reason each software block needs to manipulate with own PCA module control register which is in SFR space. Okay, at first attempt I just included its address into look-up table so my "universal" subroutine is able to do something like:

MOV A,#MY_CCAPM_ADDR_DIMENSION
MOVC A,@A+DPTR

And now accumulator has the address of corresponded SFR, and... and what? I cannot access it directly anyhow! (=
Okay, I set down and thought about. Then I produce the new code which works:

MOV A,#MY_CCAPM_VECTOR
MOVC A,@A+DPTR
INC AUXR1      ; select another DPTR
MOV DPTR,#CCAPM_MODIFY
JMP @A+DPTR
LABEL:
INC AUXR1      ; restore base lookup pointer
; .....

and

CCAPM_MODIFY:
XRL CCAPM0,#CONTROL_MASK
LJMP LABEL
XRL CCAPM1,#CONTROL_MASK
LJMP LABEL
XRL CCAPM2,#CONTROL_MASK
LJMP LABEL
XRL CCAPM3,#CONTROL_MASK
LJMP LABEL
XRL CCAPM4,#CONTROL_MASK
LJMP LABEL

Yes, you know, you know! (= I used 0,6,12,18 values at DPTR+MY_CCAPM_VECTOR...
Now the question: all works good but I do not like such way - it looks not aesthetically (=
Any suggestions? Fresh ideas?

Thank you!
