HcInterruptEnable register (R/W: 04H/84H)
Each enable bit in the HcInterruptEnable register corresponds to an associated
interrupt bit in the HcInterruptStatus register. The HcInterruptEnable register is used
to control which events generate a hardware interrupt. A hardware interrupt is
requested on the host bus when three conditions occur:
A bit is set in the HcInterruptStatus register
The corresponding bit in the HcInterruptEnable register is set
Bit MasterInterruptEnable is set.
Writing a logic 1 to a bit in this register sets the corresponding bit, whereas writing a
logic 0 to a bit in this register leaves the corresponding bit unchanged. On a read, the
current value of this register is returned.
