Section 13 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.
