MB_Sleep16roRead-only0x0PMU processing mode:
0: active.
1: sleep.
Read-only.
Write_QOS15:12rwNormal read/write0x8QoS regulator setting used by PMU for AXI Write requests.
4-bit read/write.
Read_QOS11:8rwNormal read/write0x8QoS regulator setting used by PMU for AXI Read requests.
4-bit read/write.
Reserved 7:5roRead-only0x0reserved

0: outside of APU coherency.
1: coherent using the legacy ACP port on the APU.
SLVERR_Enable 1rwNormal read/write0x0Enable the SLVERR error signal back to the interconnect when a Register Access Error occurs.
0: disable error signal.
1: assert error signal; write data is ignored and reads returns 0.
Dont_Sleep 0rwNormal read/write0x0PMU wake-up when the PMU is in sleep mode and the interrupts are disabled.
