external master receives a transfer error acknowledge when attempting to access a register
in user mode.

The DECRAM occupies addresses from 0x2F 8000 to 0x2F . The DCCR block occupies
addresses from 0x2F A000 to 0x2F A03F.
The address for non-implemented memory blocks is not acknowledged, and causes an error
condition.
