1. PnINT bits are within the range from P0INT to P6INT.
This bit is cleared when the interrupt source is served.
This bit is set when an interrupt is triggered by the endpoint n (UPSTAn). This triggers a USB interrupt if the corresponding pipe
interrupt enable bit is one (UHINTE register).
This bit is cleared when the HWUPIC bit is written to one.
This bit is set when:
- the host controller is in the suspend mode (SOFE is zero) and an upstream resume from the peripheral is detected.
- the host controller is in the suspend mode (SOFE is zero) and a peripheral disconnection is detected.
- the host controller is in the Idle state (VBUSRQ is zero, no VBUS is generated), and an SRP event initiated by the peripheral is
detected (USBSTA.SRPI is one).
This interrupt is generated even if the clock is frozen by the FRZCLK bit.
This bit is cleared when the HSOFIC bit is written to one.
This bit is set when a SOF is issued by the Host controller. This triggers a USB interrupt when HSOFE is one. When using the
host controller in low speed mode, this bit is also set when a keep-alive is sent.
This bit is set when an Upstream Resume has been received from the Device.
This bit is cleared when the RXRSMIC is written to one.
This bit is cleared when the RSMEDIC bit is written to one.
This bit set when a Downstream Resume has been sent to the Device.
This bit is cleared when the RSTIC bit is written to one.
This bit is set when a USB Reset has been sent to the device.
