RT Config issue

I have been successfully using DT's RTCONFIG with an offset,
For example

@ ReadConfig?CB _CONFIG1H, _OSCTYPE


But when I try to use the line

@ ReadConfig?BB 200000h, _User1

I get the error message

"Register in operand not in bank0. Ensure that bank bits are correct."

Can someone tell me what I'm doing wrong?

HI Charles,

The @ ReadConfig?BB macro uses a BYTE variable as an offset from 300000h (CONFIG space). It can't read the ID locations (200000).

You can read them with the ?CB macro ...

Code:

---

@ ReadConfig?CB 200000h, _User1
    --OR--
@ ReadConfig?CB _IDLOC0, _User1

---

Or you could add this macro to the RTconfig include, which will let you use an offset from the first ID loc...

Code:

---

ReadID?BB  macro  Breg, Bout
        movlw    upper(_IDLOC0)
        movwf    TBLPTRU, A
        movlw    high(_IDLOC0)
        movwf    TBLPTRH, A
        movff    Breg, TBLPTRL
        TBLRD*                            ; read the ID byte
        movff    TABLAT, Bout
    endm

---

Then you could ...

Code:

---

FOR X = 7 to 0 STEP -1
    @ ReadID?BB  _X, _User1
    LCDOUT HEX2 User1
NEXT X

---

Thanks!

I should have looked at your code for the answer, but it is month-end around here and I don't even have time to do anything constructive!
