3.5.3

Serial Port UART1 RS232

The UART1 is buffered with an Analog Devices ADM3312E RS-232 transceiver and is connected to the HE10 PIO
port C. A classic implementation RS232 transceiver selection should include double source capability.

Features:



One RS232 transceiver connected to RXD (PC1) and TXD (PC0) only



One HE10 male connector (PIO port C)



Required resistors and capacitors
