11.2 USB legacy support registers
The ISP1561 supports legacy keyboards and mice. Four operational registers are
used to provide the legacy support. Each of these registers is located on a 32-bit
boundary. The offset of these registers is relative to the base address of the Host
Controller operational registers with HceControl located at offset 100H.
11.2.1
HceControl register (address: value read from func0 or func1 of address
10H + 100H)
