11.3.1 auto_psv Memory Space

The PSV feature allows the mapping of one 32K page of Flash into the upper 32K of the data address space via the Special Function Register (SFR) PSVPAG or DSRPAG. By default, the compiler only supports direct access to one single PSV page, referred to as the auto_psv space. In this model, DSC data pointers can be used. However, this can make it difficult to manage large amounts of constant data stored in Flash on larger devices.
