21. UART0
UART0 is an enhanced serial port with frame error detection and address recognition hardware. UART0
may operate in full-duplex asynchronous or half-duplex synchronous modes, and mutiproccessor commu-
nication is fully supported. Receive data is buffered in a holding register, allowing UART0 to start reception
of a second incoming data byte before software has finished reading the previous data byte. A Receive
Overrun bit indicates when new received data is latched into the receive buffer before the previously
received byte has been read.
UART0 is accessed via its associated SFR’s, Serial Control (SCON0) and Serial Data Buffer (SBUF0). The
single SBUF0 location provides access to both transmit and receive registers. Reading SCON0 accesses
the Receive register and writing SCON0 accesses the Transmit register.
UART0 may be operated in polled or interrupt mode. UART0 has two sources of interrupts: a Transmit
Interrupt flag, TI0 (SCON0.1) set when transmission of a data byte is complete, and a Receive Interrupt
flag, RI0 (SCON0.0) set when reception of a data byte is complete. UART0 interrupt flags are not cleared
by hardware when the CPU vectors to the interrupt service routine; they must be cleared manually by soft-
ware. This allows software to determine the cause of the UART0 interrupt (transmit complete or receive
complete).
