C251: LARGE DIRECTIVE

Information in this article applies to:

• C251 Version 1.24
• C251 Version 2.14

QUESTION

What does the LARGE memory model allow me to do?

ANSWER

In the LARGE memory model, all variables and local data segments of functions and procedures reside (as defined) in the xdata memory of the 251 system. Up to 64 Kbytes of xdata memory may be accessed. This requires the long and therefore inefficient form of data access through the data pointer.

MORE INFORMATION

• Refer to LARGE in the Cx51 User's Guide.
