Data Format
The UART channel can be used to communicate with a master microprocessor or as a
slave microprocessor, both of which exhibit transmit and receive functionality. You can
either operate the UART channel by polling the UART Status register or via interrupts.
The UART remains active during HALT mode. If neither the transmitter nor the receiver is
enabled, the UART baud rate generator can be used as an additional timer. The UART
contains a noise filter for the receiver that can be enabled.
The UART always transmits and receives data in an 8-bit data format, with the least-
significant bit occurring first. An even or odd parity bit can be optionally added to the data
stream. Each character begins with an active Low Start bit and ends with either 1 or 2
active High Stop bits.
format employed by the UARTs without parity and with parity, respectively.
