34.6.7
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 UDP_CSR0:
EP0INT is a sticky bit. Interrupt remains valid until EP0INT is cleared by writing in the corresponding UDP_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 UDP_CSR1:
EP1INT is a sticky bit. Interrupt remains valid until EP1INT is cleared by writing in the corresponding UDP_CSR1 bit.
