Section 22 USB Pin Multiplex Controller
Section 22 USB Pin Multiplex Controller
22.1 Feature
The USB multiplex controller controls the data path to USB transceiver from USB host controller
port 1 or USB function controller.
Both USB host port 1 and USB function controller are connected to USB transceiver 1 via
multiplexer that is controlled by EXPFC register. The USB host controller port 2 and USB
transceiver 2 are connected one-to-one. USB transceiver 1 can be connected to USB host
controller or USB function controller, while USB transceiver 2 can only be connected to the USB
host controller. Because these ports and transceivers are controlled individually, USB transceiver 2
can be connected to either the USB host controller or the USB function controller regardless its
status. The signals to USB transceiver are used as external pins USB1d _**** which are
multiplexed with pins 113 to 122.
