10.3.2.1 Data Region

data  (a!xr)   : ORIGIN = 0x4000,        LENGTH = 0x4000

The data region corresponds to the RAM memory of the dsPIC33AK128MC106 device, and is used for both initialized and uninitialized variables. The starting address of region data is 0x4000.

The expression in parentheses instructs the linker to allocate unmapped sections that are allocatable, but not executable or read-only, in this region.
