13.1.5 DcInterruptEnable register (R/W: C3H/C2H)
This command is used to individually enable or disable interrupts from all endpoints,
as well as interrupts caused by events on the USB bus (SOF, SOF lost, EOT,
suspend, resume, reset). That is, if an interrupt event occurs while the interrupt is not
enabled, nothing will be seen on the interrupt pin. Even if you then enable the
interrupt during the interrupt event, there will still be no interrupt seen on the interrupt
pin, see
The DcInterrupt register will not register any interrupt, if it is not already enabled
using the DcInterruptEnable register. The DcInterruptEnable register is not an
Interrupt Mask register.
A bus reset will not change any of the programmed bit values.
The command accesses the DcInterruptEnable register, which consists of 4 bytes.
The bit allocation is given in
