There are four types of transfers defined for the endpoints. Control transfers are used to
configure the device.
Interrupt transfers are used for periodic data transfer. Bulk transfers are used when the
latency of transfer is not critical. Isochronous transfers have guaranteed delivery time but
no error correction.
The USB device controller on the PN7462 family enables full-speed (12 Mbit/s) data
exchange with a USB host controller.
The picture below shows the block diagram of the USB device controller.
