This register enables or disables individual interrupt sources. The interrupt for each
endpoint can individually be controlled through the associated IEPnRX or IEPnTX bits,
here n represents the endpoint number. All interrupts can globally be disabled through
bit GLINTENA in the Mode register (see
An interrupt is generated when the USB SIE receives or generates an ACK or NAK on the
USB bus. The interrupt generation depends on Debug mode settings of bit fields
CDBGMOD[1:0], DDBGMODIN[1:0] and DDBGMODOUT[1:0].
All data IN transactions use the Transmit buffers (TX) that are handled by DDBGMODIN
bits. All data OUT transactions go through the Receive buffers (RX) that are handled by
DDBGMODOUT bits. Transactions on control endpoint 0 (IN, OUT and SETUP) are
handled by CDBGMOD bits.
Interrupts caused by events on the USB bus (SOF, suspend, resume, bus reset, set up
and high-speed status) can also be individually controlled. A bus reset disables all
enabled interrupts, except bit IEBRST (bus reset) that remains unchanged.
The DcInterruptEnable register consists of 4 bytes. The bit allocation is given in
