Section 15 Serial Communication Interface (SCI, IrDA)
Bit 7—Transmit Interrupt Enable (TIE): Enables or disables transmit-data-empty interrupt
(TXI) request generation when serial transmit data is transferred from TDR to TSR and the TDRE
flag in SSR is set to 1.
Bit 7
TIE
0
1
Note:
Bit 6—Receive Interrupt Enable (RIE): Enables or disables receive-data-full interrupt (RXI)
request and receive-error interrupt (ERI) request generation when serial receive data is transferred
from RSR to RDR and the RDRF flag in SSR is set to 1.
Bit 6
RIE
0
1
Note:
Bit 5—Transmit Enable (TE): Enables or disables the start of serial transmission by the SCI.

* TXI interrupt request cancellation can be performed by reading 1 from the TDRE flag,
* RXI and ERI interrupt request cancellation can be performed by reading 1 from the
2. In this state, serial transmission is started when transmit data is written to TDR and the
then clearing it to 0, or clearing the TIE bit to 0.
RDRF, FER, PER, or ORER flag, then clearing the flag to 0, or clearing the RIE bit to 0.
TDRE flag in SSR is cleared to 0.
SMR setting must be performed to decide the transmission format before setting the TE
bit to 1.
