•
When fetching 32 bits of decompressed instruction from the DECRAM, each 16 bits will be read
from different RAM banks.
The DCCR registers should be programmed with data supplied by the code compression tool, in order to
be correlated with the compressed code.
,
1. The DCCR0 register is hard coded for the “bypass decompressor class.” Write accesses do not affect the DCCR0 register. The
DCCR0 register will always return 0x0000 0000 when read.
