MPC562/MPC564 Compression Features
A.2.14
The MPC562/MPC564 allows the option to switch between compressed and non-compressed code on the
fly. There are two ways to switch between the modes, as shown in
Definition for Exception
A.2.14.1
The MPC562/MPC564 can wake up upon reset with all the exception handlers defined to be compressed
(or not), so when any exception occurs or completes, the hardware switches to the appropriate mode
without software intervention.
A.2.14.2
If the compression mode is enabled on the MPC562/MPC564, the software can switch between
compressed and non-compressed code by setting (or clearing) the compression mode bit in the RCPU
MSR register. This is done by setting/clearing bit 29 in the RCPU SRR1 register (SRR1 gets loaded into
the MSR register when the rfi instruction is executed. Bit 29 is the DCMPEN bit of the MSR). The next
step is to load SRR0 with a target address in compressed/non-compressed format and then executing an rfi
instruction. Following is a suggested routine to execute the switch in both directions (must be run in
supervisor mode when RCPU MSR[PR] bit is cleared):
A.3
A.3.1
The MPC562/MPC564 provides two instruction fetch modes: decompression off and decompression on.
The operational modes are defined by RCPU MSR[DCMPEN] bit. If the bit is set, the mode is
decompression on. Otherwise, it is in decompression off.

When BBCMCR[EN_COMP] (bit 21) is set, modification of
MSR[DCMPEN] (bit 29) by mtmsr instruction is strictly forbidden. It may
cause the machine to hang until reset.
