5.1
The 56F8006/56F8002 device is based on the 56800E core. It uses a dual Harvard-style architecture with two independent
memory spaces for Data and Program. On-chip RAM is shared by both data and program spaces and flash memory is used only
in program space.

The 56F8006/56F8002 series provide up to 16 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 and written to program memory space through primary data memory buses: CDBW for data write and CDBR for data read.
Accessing program memory space over the data memory buses takes longer access time compared to 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.
