The paged memory scheme provides access to

multiple 32-Kbyte windows in the EDS and PSV

memory. The Data Space Page registers, DSxPAG, in

combination with the upper half of the Data Space

address, can provide up to 16 Mbytes of additional

address space in the EDS and 8 Mbytes (DSRPAG

only) of PSV address space. The paged data memory

space is shown in Figure 4-11.

The Program Space (PS) can be accessed with a

DSRPAG of 0x200 or greater. Only reads from PS are

supported using the DSRPAG. Writes to PS are not

supported, therefore, the DSWPAG is dedicated to DS,

including EDS. The Data Space and EDS can be read

from and written to using DSRPAG and DSWPAG,

respectively.
