Embedded Flash
There is totally 8 Kbyte flash embedded in the MPC82x52A.
The user can configure the whole flash to store his 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 MPC82x52A is spanning over 1FFFH, the device will do nothing.
The user can develop the ISP program, and put it into the embedded flash that addressed
from 1400H, 1800H, or 1C00H, meanwhile configure OR0 [5:4], and set OR0 [3] to 0, and
direct the device to boot from the 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].
