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.
