Page Register
The 8-bit Page Register increases the addressing
capability ofthe MCUCore bya factorof upto 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 in the Sector Select (FS0-
FS7, CSBOOT0-CSBOOT3), and SRAM Select
(RS0) equations.
If memory paging is notneeded, 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 57 shows the Page Register. The eight flip-
flops in the register are connected to the internal
data bus D0-D7. The MCU can write to or read
from thePage Register. The Page Register can be
accessed at address location CSIOP + E0h.
