PAGE REGISTER
The 8-bit Page Register increases the addressing
capability of the MCU by a factor of up to 256. The
contents of the register can also be read by the
MCU. The outputs of the Page Register (PGR0-
PGR7) are inputs to the DPLD decoder and can be
included
CSBOOT0-CSBOOT3), and SRAM Select (RS0)
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 AN1154.

flops in the register are connected to the internal
data bus D0-D7. The MCU can write to or read
from the Page Register. The Page Register can be
accessed at address location CSIOP + E0h.
