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 a logic 1 to a bit in this
register clears the corresponding bit in the HcInterruptEnable register, whereas
writing a logic 0 to a bit in this register leaves the corresponding bit in the
HcInterruptEnable register unchanged. On a read, the current value of the
HcInterruptEnable register is returned.
