Section 17 Serial Communication Interface (SCI)
Bit 7—Transmit Interrupt Enable (TIE): Enables or disables the transmit-data-empty interrupt
(TXI) requested when the transmit data register empty bit (TDRE) in the serial status register
(SCSSR) is set to 1 due to transfer of serial transmit data from the SCTDR to the SCTSR.
Bit 7: TIE
0
1
Note: * The TXI interrupt request can be cleared by reading TDRE after it has been set to 1, then
Bit 6—Receive Interrupt Enable (RIE): Enables or disables the receive-data-full interrupt (RXI)
requested when the receive data register full bit (RDRF) in the serial status register (SCSSR) is set
to 1 due to transfer of serial receive data from the SCRSR to the SCRDR. It also enables or
disables receive-error interrupt (ERI) requests.
Bit 6: RIE
0
1
Note: * RXI and ERI interrupt requests can be cleared by reading the RDRF flag or error flag
Bit 5—Transmit Enable (TE): Enables or disables the SCI serial transmitter.
Bit 5: TE

Notes: 1. The transmit data register empty bit (TDRE) in the serial status register (SCSSR) is
Bit 4—Receive Enable (RE): Enables or disables the SCI serial receiver.
