RTX166 TINY: USER STACK POINTER ADDRESSING VIA DPP3


Information in this article applies to:

  • C166 All Versions

QUESTION

I have allocated the user stack pointer to the DPP3 register as explained in the Getting Started User's Guide, Creating Applications, Applications without external RAM Devices. But now it seems that my RTX Tiny application is unstable. Is there something that I need to consider?

ANSWER

Yes, you also need to rebuild the RTX TINY library with the DPP3 setting for USRSTK_DPP in the file RTX166T.A66.

USRSTK_DPP   LIT  'DPP3'   ; change setting to DPP3 if the user stack is
                           ; located in the SDATA/IDATA memory class
