To re-enable the interrupt generation:
Remark: The InterruptPinEnable bit in the HcHardwareConfiguration register latches the
interrupt output. When this bit is set to logic 0, the interrupt output will remain unchanged,
regardless of any operations on the interrupt control registers.
If INT1 is asserted, and the Host Controller Driver (HCD) wishes to temporarily mask off
the INT signal without clearing the HcμPInterrupt register, the following procedure should
be followed:
To re-enable the interrupt generation:
The ISP1160/01’s USB HC has four USB states—USBOperational, USBReset,
USBSuspend and USBResume—that define the HC’s USB signalling and bus states
responsibilities. The signals are visible to the Host Controller Driver (HCD) via the
ISP1160/01 USB HC’s control registers.
1. Set all bits in the HcμPInterrupt register.
2. Set the InterruptPinEnable bit to logic 1.
1. Make sure that the InterruptPinEnable bit is set to logic 1.
2. Clear all bits in the HcμPInterruptEnable register.
3. Set the InterruptPinEnable bit to logic 0.
1. Set all bits in the HcμPInterruptEnable register according to the HCD requirements.
2. Set the InterruptPinEnable bit to logic 1.
