15.0
This section describes the Universal Asynchronous
Receiver/Transmitter Communications module. The
dsPIC30F2011/2012/3012 processors have one UART
module (UART1). The dsPIC30F3013 processor has
two UART modules (UART1 and UART2).

The key features of the UART module are:
• Full-duplex, 8 or 9-bit data communication
• Even, odd or no parity options (for 8-bit data)
• One or two Stop bits
• Fully integrated Baud Rate Generator with 16-bit
• Baud rates range from 38 bps to 1.875 Mbps at a
• 4-word deep transmit data buffer
• 4-word deep receive data buffer
• Parity, framing and buffer overrun error detection
• Support for interrupt only on address detect
• Separate transmit and receive interrupts
• Loopback mode for diagnostic support
• Alternate receive and transmit pins for UART1
