These bits select the Serial Port Operation Mode.
The function of this bit is dependent on the Serial Port Operation Mode.
Mode 0: No effect
Mode 1: Checks for valid stop bit.
Mode 2 and 3: Multiprocessor Communications Enable.
This bit enables/disables the UART receiver.
0: UART reception disabled.
1: UART reception enabled.
TB8: Ninth Transmission Bit.
The logic level of this bit will be assigned to the ninth transmission bit in Modes 2 and 3. It
is not used in Modes 0 and 1. Set or cleared by software as required.
RB8: Ninth Receive Bit.
The bit is assigned the logic level of the ninth bit received in Modes 2 and 3. In Mode 1, if
SM2 is logic 0, RB8 is assigned the logic level of the received stop bit. RB8 is not used in
Mode 0.
Set by hardware when a byte of data has been transmitted by the UART (after the 8
Mode 0, or at the beginning of the stop bit in other modes). When the UART interrupt is
enabled, setting this bit causes the CPU to vector to the UART interrupt service routine.
This bit must be cleared manually by software
Set by hardware when a byte of data has been received by the UART (after the 8
Mode 0, or after the stop bit in other modes – see SM2 bit for exception). When the
UART interrupt is enabled, setting this bit causes the CPU to vector to the UART interrupt
service routine. This bit must be cleared manually by software.
SM2: Multiprocessor Communication Enable.
REN: Receive Enable.
TI: Transmit Interrupt Flag.
RI: Receive Interrupt Flag.
