14.2.6
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.
Note: * The TXI interrupt request can be cleared by reading TDRE after it has been set to 1, then
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.
Note: * RXI and ERI interrupt requests can be cleared by reading the RDRF flag or error flag
