5.4.1 Near Data Memory

A 64 Kbyte address space, referred to as near data memory, is reserved in the data memory space between 0x00_0000 and 0x01_0000. Near data memory is directly addressable through a 16-bit absolute address field within all file register instructions.

The memory regions included in the near data region will depend on the amount of data memory implemented for each dsPIC33AK128MC106 device variant. At a minimum, the near data region will include all of the SFRs and some of the X data memory. For devices that have smaller amounts of data memory, the near data region can include all of X memory space and possibly some or all of Y memory space. Refer to Figure 5-1 for more details.

Note: The entire 64 Kbyte near data space can be addressed directly using the MOV instruction. Refer to the dsPIC33A Programmer’s Reference Manual”, available from www.microchip.com, for further details.
