Table D-3 is the TPURAM address map. TPURAM responds to both program and data
space accesses. The RASP bit in the TRAMMCR determines whether the processor
must be operating at the supervisor privilege level to access the array. TPURAM con-
trol registers are accessible at the supervisor privilege level only.
Y = M111, where M is the logic state of the module mapping (MM) bit in the SIMCR.
This bit controls whether the RAM array is in stop mode or normal operation. Reset
state is zero, for normal operation. In stop mode, the array retains its contents, but can-
not be read or written by the CPU.
TRAMTST is used for factory test of the TPURAM module.
These bits specify address lines ADDR[23:11] of the base address of the TPURAM
array when enabled.

Access
0 = TPURAM array operates normally.
1 = TPURAM array enters low-power stop mode.
0 = TPURAM array is accessible from the supervisor or user privilege level.
1 = TPURAM array is accessible from the supervisor privilege level only.
