The four index bits of the PPAGE register select a 16K page in the global memory map
selected 16K page is mapped into the paging window ranging from local address 0x8000 to 0xBFFF.
Figure 5-9
CPU has special access to read and write this register directly during execution of CALL and RTC
instructions.
The fixed 16KB page from 0x0000 to 0x3FFF is the page number 0xC. Parts of this page are covered by
Registers, EEPROM and RAM space. See SoC Guide for details.
The fixed 16KB page from 0x4000–0x7FFF is the page number 0xD.
