The interrupt generation depends on the type of mode setting specified in the register;
see
DDBGMODOUT is for the OUT pipe. The register sets the interrupt to the level or pulse
trigger by using the INTLVL bit. The polarity of the interrupt signal is control by INTPOL.
Table 3.
The typical function of the Interrupt Configuration register is to enable the ACK interrupt.
Fig 3
interrupt signal that will be generated on the INT pin when an ACK condition occurs.
The following sample code programs the IN endpoint interrupt to all ACK conditions;
OUT endpoint, interrupt to all ACK and NYET condition, control endpoint interrupt to all
ACK conditions:
