RAMSIZE Linker Directive

RS

RAMSIZE (bytes)

RAMSIZE (128)

This information is automatically set using information from the Device Database.

The RAMSIZE directive specifies the number of bytes of DATA and IDATA in your target 8051 device. The number of bytes specified must be between 64 and 256.

Note

• The information needed to specify correct values for the RAMSIZE directive may be found in the device data sheet. Many data sheets refer to the DATA and IDATA memory as on-chip RAM. However, some devices have additional on-chip RAM that is mapped into XDATA memory space. Since the size of DATA and IDATA is limited to 256 bytes, if the on-chip RAM of your 8051 derivative is more than 256 bytes some of that RAM is most likely accessed as XDATA. Review your device data sheet carefully.
