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 31-3 Unimplemented: Read as ‘0’
bit 2-0 FRMH<2:0>: The Upper 3 bits of the Frame Numbers bits
The register bits are updated with the current frame number whenever a SOF TOKEN is received.
