A.2.13
In order to commence the execution of the compressed code, the DECRAM and the class information (in
the DCCR registers) must be programmed. The data to be programmed is supplied by the compressor tool
and the vocabulary generator. There are two initialization scenarios:
Freescale Semiconductor
1. Wake up in decompression off mode — If the chip wakes up with decompression disabled, the
2. Wake up in decompression on mode — If the chip wakes up in decompression on mode, it has to

initialization routine can be executed at any time before entering decompression on mode. After
the compression environment is initialized, the operational mode would be changed to
decompression on.
process compressed instructions without the vocabularies and class parameters. Thus, all
instructions executed until the end of the initialization routine should be compressed in the global
bypass format. DECRAM loading is an essential part of this intialization routine. After DECRAM
loading, efficient compressed code may be used.
