Multipacket transfer enables a data payload exceeding the maximum packet size of an endpoint to be transferred as
multiple packets without software intervention. This reduces the CPU intervention and the interrupts needed for USB
transfers.
For low-power operation, the USB module can put the microcontroller into any sleep mode when the USB bus is idle and
a suspend condition is given. Upon bus resumes, the USB module can wake up the microcontroller from any sleep
mode.
PORTD has one USB. Notation of this is USB.
