36.6.6 UDP Interrupt Mask Register
Name:UDP_IMR
Access:Read-only
EP0INT: Mask Endpoint 0 Interrupt
EP1INT: Mask Endpoint 1 Interrupt
EP2INT: Mask Endpoint 2 Interrupt
EP3INT: Mask Endpoint 3 Interrupt
EP4INT: Mask Endpoint 4 Interrupt
EP5INT: Mask Endpoint 5 Interrupt
0: Corresponding Endpoint Interrupt is disabled.
1: Corresponding Endpoint Interrupt is enabled.
RXSUSP: Mask UDP Suspend Interrupt
0: UDP Suspend Interrupt is disabled.
1: UDP Suspend Interrupt is enabled.
RXRSM: Mask UDP Resume Interrupt.
0: UDP Resume Interrupt is disabled.
1: UDP Resume Interrupt is enabled.
EXTRSM: Mask External Resume Interrupt
0: UDP External Resume Interrupt is disabled.
1: UDP External Resume Interrupt is enabled.
SOFINT: Mask Start Of Frame Interrupt
0: Start of Frame Interrupt is disabled.
1: Start of Frame Interrupt is enabled.
BIT12: UDP_IMR Bit 12
Bit 12 of UDP_IMR cannot be masked and is always read at 1.
WAKEUP: USB Bus WAKEUP Interrupt
0: USB Bus Wakeup Interrupt is disabled.
1: USB Bus Wakeup Interrupt is enabled.
Note: When the USB block is in suspend mode, the application may power down the USB logic. In this case, any USB HOST resume
request that is made must be taken into account and, thus, the reset value of the RXRSM bit of the register UDP_IMR is
enabled.
