Data Sheet
22.12.3
Reset value EPIR0: 11
The interrupts contained in the EPIRn register can individually be masked in the EPIEn
register.
An EPIR register is available for each of the 16 endpoints (n=0-15).
SODIEn Start of Data Interrupt Enable
EPIRn.4 Not implemented. Reserved for future use.

Bit SODIEn enables the generation of an endpoint specific start of data
interrupt when bit SODn in register EPIRn is set.
Endpoint Interrupt Request Register (EPIRn)
USB Acknowledge
Bit ACKn=1 indicates a successful action on the USB.
USB Not Acknowledge
Bit NACK is set for all unsuccessful actions on the USB.
Read Length Error
Bit RLEn is automatically set if the number of bytes read by the USB does
not correspond to the packet length programmed by the CPU.
A mismatch in packet size will not cause a data packet to be discarded.
The RLEn bit gets automatically cleared if there is a USB reset
(RESUBF = 1) or if Interrupt flags are cleared upon read of EPIRn.
Data Not Ready
This bit is set by hardware if the USB module requires an access to USB
memory, but no buffer is available.
USB Read Action: DNRn is set if UBF is not set.
USB Write Action: DNRn is set if UBF is set.
No Data
This bit indicates an incorrect CPU read or write access to USB memory. It
is set if the CPU processes a read access to an empty USB buffer or a write
access to a full buffer. NODn is also set if the direction is write (DIRn=0 for
USB write access) and the CPU tries to write to the USB memory buffer.
