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 15-6
bit 5-0
VPR<9:0>: These registers store the digitized value of the latest representation of the power relative
to maximum power.
Unimplemented: Read as ‘0’
