UARTs (Universal Asynchronous Receiver Transmitter) FAQ

How is the bus interface mode selected?

The bus interface mode is selected using the 16/68 pin. A logic 1 or unconnected state selects the Intel bus (16 mode), while a logic 0 selects the Motorola bus (68 mode).

What is the maximum data rate supported?

The device supports serial data rates up to 5 Mbit/s when used with an external 80 MHz clock.

Does the device support infrared communication?

Yes, it includes a built-in IrDA encoder/decoder supporting IrDA version 1.0 with speeds up to 115.2 kbit/s.
