Embedded Flash
MEGAWIN
There is totally 15.5 Kbyte flash embedded in the MPC82x54A.
The user can configure the whole flash to store the application program, can configure the
flash for both storage of application (AP) program and In-System-Program (ISP) code, or
even can configure the flash for storage of AP, ISP, and In-Application-Program (IAP) memory.
While the program counter of MPC82x54A is spanning over 3DFF
The user can develop own ISP program, and put it into the embedded flash that addressed
from 3000
direct the device to boot from own ISP code.
If there is requirement from the user’s application program to store nonvolatile parameters,
the user can allocate part of the embedded flash as IAP memory by configure OR1 [7:1].
