A.2.9.2
This MPC562/MPC564 instruction is compressed into a single segment. The vocabulary table pointer
points to an offset in tables of all RAMs (DECRAMs).
The definition of the class includes:
Data brought from RAM#1 is the 16 MSBs of the decompressed instruction and data brought from
RAM#2 is the 16 LSBs of the decompressed instruction.
A.2.9.3
This MPC562/MPC564 instruction is divided into two segments. Each segment is compressed and mapped
into a different vocabulary. The vocabularies reside in different RAMs. Proper programming can swap the
vocabularies’ locations.
The definition of the class includes:
