Section 12 Serial Communication Interface (SCI)
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.

Note:* RXI and ERI interrupt request cancellation can be performed by reading 1 from the RDRF
Bit 5—Transmit Enable (TE): Enables or disables the start of serial transmission by the SCI.
