There are two groups of interrupts represented by group 1 and group 2 in
A pair of registers control each group.
Group 2 contains six possible interrupt events (recorded in the HcInterruptStatus
register). On occurrence of any of these events, the corresponding bit would be set to
logic 1; and if the corresponding bit in the HcInterruptEnable register is also logic 1,
the 6-input OR gate would output a logic 1. This output is AND-ed with the value of
MIE (bit 31 of HcInterruptEnable). Logic 1 at the AND gate will cause bit OPR in the
Hc PInterrupt register to be set to logic 1.
Group 1 contains six possible interrupt events, one of which is the output of group 2
interrupt sources. The Hc PInterrupt and Hc PInterruptEnable registers work in the
same way as the HcInterruptStatus and HcInterruptEnable registers in the interrupt
group 2. The output from the 6-input OR gate is connected to a latch, which is
controlled by InterruptPinEnable (bit 0 of the HcHardwareConfiguration register).
In the event in which the software wishes to temporarily disable the interrupt output of
the ISP1161A1 Host Controller, the following procedure should be followed:
1. Make sure that bit InterruptPinEnable in the HcHardwareConfiguration register is
2. Clear all bits in the Hc PInterrupt register.
3. Set bit InterruptPinEnable to logic 0.
