Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 31-16 Unimplemented: Read as ‘0’
bit 15-10 BMXDUDBA<15:10>: DRM User Data Base Address bits
When non-zero, the value selects the relative base address for User mode data space in RAM, the value
must be greater than BMXDKPBA.
bit 9-0 BMXDUDBA<9:0>: Read-Only bits
Value is always ‘0’, which forces 1 KB increments
Note 1: At Reset, the value in this register is forced to zero, which causes all of the RAM to be allocated to Kernal
mode data usage.
2: The value in this register must be less than or equal to BMXDRMSZ.
