13.2.6
SCR is a register that performs enabling or disabling of SCI transfer operations, serial clock output
in asynchronous mode, and interrupt requests, and selection of the serial clock source.
SCR can be read or written to by the CPU at all times.
SCR is initialized to H'00 by a reset and in hardware standby mode. It retains its previous state in
module stop mode, software standby mode, watch mode, subactive mode, and subsleep mode.
Bit 7—Transmit Interrupt Enable (TIE): Enables or disables transmit data empty interrupt
(TXI) request generation when serial transmit data is transferred from TDR to TSR and the TDRE
flag in SSR is set to 1.
Note: TXI interrupt request cancellation can be performed by reading 1 from the TDRE flag, then
