22.3.3 Usage Notes
About the USB Transceiver
USB transceiver is included in the SH7727. it is also possible to connect an external transceiver
according to the setting in EXPFC register (see figures 22.4, 22.5, and 22.7). In this case, ask the
manufacturer of the transceiver about the recommended circuit that is used between the USB
transceiver and USB connectors.
About the Examples of External Circuit
These examples of transceiver connection in this chapter are for reference only, therefore proper
operation is not guaranteed with these circuit examples. If system countermeasures are required
for external surges and ESD noise, use a protective diode, etc.
