USB Interrupt Status Register
Register Name:
Access Type:
• EP0INT: Endpoint 0 Interrupt Status
0 = No Endpoint0 Interrupt pending.
1 = Endpoint0 Interrupt has been raised.
Several signals can generate this interrupt. The reason can be found by reading USB_CSR0:
EP0INT is a sticky bit. Interrupt remains valid until EP0INT is cleared by writing in the corresponding USB_CSR0 bit.
• EP1INT: Endpoint 1 Interrupt Status
0 = No Endpoint1 Interrupt pending.
1 = Endpoint1 Interrupt has been raised.
Several signals can generate this interrupt. The reason can be found by reading USB_CSR1:
EP1INT is a sticky bit. Interrupt remains valid until EP1INT is cleared by writing in the corresponding USB_CSR1 bit.
• EP2INT: Endpoint 2 Interrupt Status
0 = No Endpoint2 Interrupt pending.
1 = Endpoint2 Interrupt has been raised.
Several signals can generate this interrupt. The reason can be found by reading USB_CSR2:
EP2INT is a sticky bit. Interrupt remains valid until EP2INT is cleared by writing in the corresponding USB_CSR2 bit.
