21.3. Frame and Transmission Error Detection
All Modes:
The Transmit Collision bit (TXCOL0 bit in register SSTA0) reads ‘1’ if user software writes data to the
SBUF0 register while a transmit is in progress.
Modes 1, 2, and 3:
The Receive Overrun bit (RXOV0 in register SSTA0) reads ‘1’ if a new data byte is latched into the receive
buffer before software has read the previous byte. The Frame Error bit (FE0 in register SSTA0) reads ‘1’ if
an invalid (low) STOP bit is detected.
