PAGE REGISTER
The 8-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,
EEPROM, 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.
Figure

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 Regis-
ter can be accessed at address location CSIOP +
E0h.
