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), which are handled by bits
DDBGMODIN. All data OUT transactions go via the Receive buffers (RX), which are
handled by bits DDBGMODOUT. Transactions on control endpoint 0 (IN, OUT and
SETUP) are handled by bits CDBGMOD.
Interrupts caused by events on the USB bus (SOF, Pseudo SOF, suspend, resume,
bus reset, setup and high-speed status) can also be individually controlled. A bus
reset disables all enabled interrupts except bit IEBRST (bus reset), which remains
unchanged.
The Interrupt Enable register consists of 4 bytes. The bit allocation is given in
Table 29
.
