20.4.2.1 Asynchronous Mode

Asynchronous mode supports standard UART communication with the following configurable options:

• 7, 8-Bit Data Width
• 1, 1.5 or 2 Stop Bits
• Even, Odd or No Parity (Ninth data bit)
• Independently Selectable TX and RX Polarity
• Address Detect (Ninth data bit)
• Auto-Baud
• Break Transmission/Detection
• Flow Control (XON/XOFF and HW)
• Half/Full-Duplex TX Pin Control
• TX and RX Interrupt Configuration

The MODE[3:0] bits (UxCON[3:0]) are used to select the High-Level Operational mode of the UART for both transmit and receive. The five Asynchronous mode selections configure data width, parity and address detect, with the rest of the configuration options as spate controls.
