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_H, the device will do nothing.

The user can develop own ISP program, and put it into the embedded flash that addressed

from 3000_H, 3400_H, or 3800_H, meanwhile configure OR0[5:4], and set OR0[3] to 0, and to

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].
