To reenable the interrupt generation:
1. Set all bits in the Hc
PInterrupt register.
2. Set the InterruptPinEnable bit to logic 1.
Remark: The InterruptPinEnable bit in the HcHardwareConguration 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 HCD wishes to temporarily mask off the INT signal
without clearing the Hc
PInterrupt register, the following procedure should be
followed:
1. Make sure that the InterruptPinEnable bit is set to logic 1.
2. Clear all bits in the Hc
PInterruptEnable register.
3. Set the InterruptPinEnable bit to logic 0.
To reenable the interrupt generation:
1. Set all bits in the Hc
PInterruptEnable register according to the HCD
requirements.
2. Set the InterruptPinEnable bit to logic 1.

Philips slave Host Controller (HC)
9.1 HC’s four USB states
The ISP1160’s USB HC has four USB states
USB Operational, USB Reset, USB
Suspend and USB Resume
that dene the HC’s USB signalling and bus states
responsibilities. The signals are visible to the HC (software) Driver via the ISP1160
USB HC’s control registers.
