15.1.6 HcInterruptDisable register (R/W: 05H/85H)
Each disable bit in the HcInterruptDisable register corresponds to an associated
interrupt bit in the HcInterruptStatus register. The HcInterruptDisable register is
coupled with the HcInterruptEnable register. Thus, writing logic 1 to a bit in this
register clears the corresponding bit in the HcInterruptEnable register, whereas
