Description

mpuzero

0

Value Meaning
0 The boot ROM maps to address 0x0 for the MPU L3 master
1 The on-chip RAM maps to address 0x0 for the MPU L3 master
This bit has no effect on non-MPU masters.
Note: Regardless of this setting, the boot ROM also always maps to address 0xFFFF0000 and the on-chip RAM also always maps to address 0xFFFD0000 for the MPU L3 master.
nonmpuzero

1

Value Meaning
0 The SDRAM maps to address 0x0 for the non-MPU L3 masters
1 The on-chip RAM maps to address 0x0 for the non-MPU masters
This bit has no effect on the MPU L3 master.

Note that regardless of this setting, the on-chip RAM also always maps to address 0xFFFD0000 for the non-MPU L3 masters.
