7593K–AVR–11/09
• 4 – HNPERRE: HNP Error Interrupt Enable Bit
Set to enable the HNPERRI interrupt. Clear to disable the HNPERRI interrupt.
• 3 – ROLEEXE: Role Exchange Interrupt Enable Bit
Set to enable the ROLEEXI interrupt. Clear to disable the ROLEEXI interrupt.
• 2 – BCERRE: B-Connection Error Interrupt Enable Bit
Set to enable the BCERRI interrupt. Clear to disable the BCERRI interrupt.
• 1 – VBERRE: VBus Error Interrupt Enable Bit
Set to enable the VBERRI interrupt. Clear to disable the VBERRI interrupt.
• 0 – SRPE: SRP Interrupt Enable Bit
Set to enable the SRPI interrupt. Clear to disable the SRPI interrupt.
• 7-6 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 5 – STOI: Suspend Time-out Error Interrupt Flag
Set by hardware when a time-out error (more than 150 ms) has been detected after a suspend.
Shall be cleared by software.
• 4 – HNPERRI: HNP Error Interrupt Flag
Set by hardware when an error has been detected during the protocol. Shall be cleared by
software.
• 3 – ROLEEXI: Role Exchange Interrupt Flag
Set by hardware when the USB controller has successfully swapped its mode, due to an HNP
negotiation: Host to Device or Device to Host. However the mode selection bit (Host/Device) is
unchanged and must be changed by firmware in order to reach the correct RAM locations and
events bits. Shall be cleared by software.
• 2 – BCERRI: B-Connection Error Interrupt Flag
Set by hardware when an error occur during the B-Connection (i.e. if Peripheral has not con-
nected after 300ms of Vbus delivery request). Shall be cleared by software.
• 1 – VBERRI: V-Bus Error Interrupt Flag
Set by hardware when a drop on VBus has been detected. Shall be cleared by software.
• 0 – SRPI: SRP Interrupt Flag
Set by hardware when a SRP has been detected. Shall be used in the Host mode only. Shall be
cleared by software.
