Section 12 Serial Communication Interface
The CPU can always read and write SCR. SCR is initialized to H'00 by a reset and in standby
mode.
Bit 7—Transmit Interrupt Enable (TIE): Enables or disables the transmit-data-empty interrupt
(TXI) requested when the TDRE flag in SSR is set to 1 due to transfer of serial transmit data from
TDR to TSR.
