12.2.6
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. In software standby mode and
module stop mode it retains its previous state.
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.
