13.2.6
The serial control register (SCSCR) operates the SCI transmitter/receiver, selects the serial clock
output in asynchronous mode, enables/disables interrupt requests, and selects the transmit/receive
clock source. The CPU can always read and write to SCSCR. SCSCR is initialized to H'00 by a
reset and in standby or module standby mode.
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 SCTDR to SCTSR.
Bit 7: TIE
0
1
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 SCRSR to SCRDR. It also enables or disables
receive-error interrupt (ERI) requests.
Bit 6: RIE
0
1
Bit 5—Transmit Enable (TE): Enables or disables the SCI serial transmitter.

Description
Transmit-data-empty interrupt request (TXI) is disabled.
The TXI interrupt request can be cleared by reading TDRE after it has
been set to 1, then clearing TDRE to 0, or by clearing TIE to 0.
Transmit-data-empty interrupt request (TXI) is enabled.
Description
Receive-data-full interrupt (RXI) and receive-error interrupt (ERI)
requests are disabled.
RXI and ERI interrupt requests can be cleared by reading the RDRF
flag or error flag (FER, PER, or ORER) after it has been set to 1, then
clearing the flag to 0, or by clearing RIE to 0.
Receive-data-full interrupt (RXI) and receive-error interrupt (ERI)
requests are enabled.
