Program Page Index Register (PPAGE)
Read: Anytime
Write: Anytime
The four index bits of the PPAGE register select a 16K page in the global memory map (
). The
selected 16K page is mapped into the paging window ranging from local address 0x8000 to 0xBFFF.
illustrates the translation from local to global addresses for accesses to the paging window. The
CPU has special access to read and write this register directly during execution of CALL and RTC
instructions.
Figure 3-9. PPAGE Address Mapping
NOTE
Writes to this register using the special access of the CALL and RTC
instructions will be complete before the end of the instruction execution.
The fixed 16KB page from 0x0000 to 0x3FFF is the page number 0xC. Parts of this page are covered by
Registers, D-Flash and RAM space. See SoC Guide for details.
The fixed 16KB page from 0x4000–0x7FFF is the page number 0xD.
