Section 13 Serial Communication Interface
Bit 4—Receive Enable (RE): Enables or disables the start of SCI serial receiving operations.
Notes: 1. Clearing the RE bit to 0 does not affect the RDRF, FER, PER, and ORER flags. These
Bit 3—Multiprocessor Interrupt Enable (MPIE): Enables or disables multiprocessor interrupts.
The MPIE setting is valid only in asynchronous mode, and only if the MP bit is set to 1 in SMR.
The MPIE setting is ignored in synchronous mode or when the MP bit is cleared to 0.
Note: * The SCI does not transfer receive data from RSR to RDR, does not detect receive errors,
Bit 2—Transmit-End Interrupt Enable (TEIE): Enables or disables the transmit-end interrupt
(TEI) requested if TDR does not contain new transmit data when the MSB is transmitted.
Note: * TEI interrupt requests can be cleared by reading the value 1 from the TDRE flag in SSR,

and does not set the RDRF, FER, and ORER flags in SSR. When it receives data in which
MPB = 1, the SCI sets the MPB bit to 1 in SSR, automatically clears the MPIE bit to 0,
enables RXI and ERI interrupts (if the RIE bit is set to 1 in SCR), and allows the FER and
ORER flags to be set.
then clearing the TDRE flag to 0, thereby also clearing the TEND flag to 0; or by clearing
the TEIE bit to 0.

flags retain their previous values.

in SMR before setting the RE bit to 1.

[Clearing conditions]
Multiprocessor interrupts are enabled *
Receive-data-full interrupts (RXI), receive-error interrupts (ERI), and setting of
the RDRF, FER, and ORER status flags in SSR are disabled until data with the
multiprocessor bit set to 1 is received.
