Program Map
The MC56F825x/MC56F824x series provide up to 64 KB on-chip flash memory. It primarily accesses through the program
memory buses (PAB; PDB). PAB is used to select program memory addresses; instruction fetches are performed over PDB.
Data can be read from and written to the program memory space through the primary data memory buses: CDBW for data write
and CDBR for data read. Access time for accessing the program memory space over the data memory buses is longer than for
accessing data memory space. The special MOVE instructions are provided to support these accesses. The benefit is that
non-time-critical constants or tables can be stored and accessed in program memory.
The program memory map appears in Table 7, Table 8, and Table 9, depending on the device.
