5.2 EHCI operational registers
5.2.1 HCCAPLENGTH register (address = 00h)
This register is used as an offset to add to register base to find the beginning of the operational register
space. The high two bytes contain a BCD encoding of the EHCI revision number supported by this host
controller. The most signification byte of this register represents a major revision and the least
signification byte is the minor revision.
