Read Only. Any attempt to write to the DECRAM array while R is set is terminated with
an error. This causes a machine check exception for RCPU.
0 DECRAM array is Readable and Writable.
1 DECRAM array is Read only.
Data Only. The DECRAM array may be used for Instructions and Data or for Data
storage only. Any attempt to load instructions from the DECRAM array, while D is set, is
terminated with an error This causes a machine check exception for the RCPU.
0 DECRAM array holds Data and/or Instruction.
1 DECRAM array holds Data only.
Supervisor Only.
When the bit is set (S = 1), only a Supervisor program may access the DECRAM. If a
Supervisor program is accessing the array, normal read/write operation will occur. If a
User program is attempting to access the array, the access will be terminated with an
error This causes a machine check exception for the RCPU.
If S = 0, the RAM array is placed in Unrestricted Space and access by both Supervisor
and User programs is allowed.
These bits can be set in Factory test mode only. The User should treat these bits as
reserved and always write as zeros.
