Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
â1â = Bit is set
U = Unimplemented bit, read as â0â
â0â = Bit is cleared
x = Bit is unknown
bit 31-16 Unimplemented: Read as â0â
bit 15-10 BMXDUPBA<15:10>: DRM User Program Base Address bits
When non-zero, the value selects the relative base address for User mode program space in RAM,
BMXDUPBA must be greater than BMXDUDBA.
bit 9-0
BMXDUPBA<9:0>: Read-Only bits
Value is always â0â, 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.
