XLarge Model

The xlarge memory model (selected with the XLARGE directive) uses the segmented mode of the C16x/ST10/XC16x microcontroller. In this memory model:

  • Variables are stored in xhuge memory when they require more space than defined by the HOLD directive.
  • Functions are stored in far memory and are accessed using far calls.

This memory model is the best choice for C16x/ST10/XC16x programs that have large code and data requirements.

Note

  • The XLARGE memory model is not available for 80C166 microcontrollers.
