bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-0 USBREQCRT<7:0>: USB Bus-Powered Required Current Amount (in units of 2 mA)
Factory default is 50 (decimal); the USB enumeration interprets this value as a current requirement of
100 mA.
