4. Explanation of Functions

4.7.4

USB Host Port External Circuits

The LSI ports have internal USB host termination resistors, including an HS termination

resistor, eliminating the need for the external components normally used to adjust

impedance. This allows a DP/DM line to be connected between the LSI terminal and the

connector. Note that the appropriate components must be used to ensure static electricity

protection and to implement EMI precautions.

An external VBUS control component is required for the VBUS.

4.8 FIFO

The LSI includes 4.5 kB of USB FIFO for use with USB data transfers. The USB FIFO capacity for

each endpoint or channel can be assigned as desired using the register settings.

Transfers are possible between the USB-I/F and CPU-I/F via the USB FIFO.
