9.1.4 Page Register
The eight bit Page Register increases the addressing capability of the microcontroller by a
factor of up to 256. The contents of the register can also be read by the microcontroller.
The outputs of the Page Register (PGR0-PGR7) are inputs to the DPLD decoder and can
be included in the Flash Memory, Flash Boot Block, and SRAM chip select equations.
If memory paging is not needed, or if not all 8 page register bits are needed for memory
paging, then these bits may be used in the CPLD for general logic. See Application
Note 57.
Figure 8 shows the Page Register. The eight flip flops in the register are connected to the
internal data bus D0-D7. The microcontroller can write to or read from the Page Register.
The Page Register can be accessed at address location CSIOP + E0h.
