These eight index bits are used to page 16 KByte blocks into the Flash page window located in the local

(CPU or BDM) memory map from address 0x8000 to address 0xBFFF (see

accessing up to 4 Mbytes of Flash (in the Global map) within the 64 KByte Local map. The PPAGE age

index register is effectively used to construct paged Flash addresses in the Local map format. The CPU has

special access to read and write this register directly during execution of CALL and RTC instructions. .

Freescale Semiconductor

Address: 0x0030

Program Page Index Register (PPAGE)

XGATE write access to this register during an CPU access which makes use

of this register could lead to unexpected results.

Writes to this register using the special access of the CALL and RTC

instructions will be complete before the end of the instruction execution.
