CNT<7:0>: SOF Threshold Value bits
Typical values of the threshold are:
01001010 = 64-byte packet
00101010 = 32-byte packet
00011010 = 16-byte packet
00010010 = 8-byte packet
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

BDTPTRL<15:9>: BDT Base Address bits
This 7-bit value provides address bits 15 through 9 of the BDT base address, which defines the starting
location of the BDT in system memory.
The 32-bit BDT base address is 512-byte aligned.
bit 0 Unimplemented: Read as ‘0’
