Clear this bit to 0 if SIRCDR and SITCDR are not used, or if all interrupts triggered by the RDRF,
TDRE, RCD and TCD bits in SISTR are to be processed by the CPU. The initial value of this bit
is 0.
Bit 9—Transmit-Control-Data-Register-Empty Interrupt Enable (TCIE): Enables the transmit-
control-data-register-empty interrupt. The initial value of this bit is 0.
Bit 8—Receive-Control-Data-Register-Full Interrupt Enable (RCIE): Enables the receive-control-
data-register-full interrupt. The initial value of this bit is 0.
Bit 7—Reserved: This bit is always read as 0. The write value should always be 0.
Bit 6—Transfer Mode Control (TM): Specifies whether the transmission synchronization signal is
to be input from an external source or generated internally by the chip. When this flag is cleared,
the transmission synchronization signal is STS pin input. When this flag is set, the transmission
synchronization signal is generated by the chip, and is output to an external device from the STS
pin. This bit does not affect reception.
Note: If the transmit mode bit (TRMD) in SIFCR is set to 1, this bit must be cleared to 0.

If TM is set to 1 and SE is set to 1 (interval mode), output of the sync signal stops at the
point at which bits T4 to T0 in SIFDR are cleared to 0 (data count of transmit data register is
zero). If TE remains set to 1 and data is written to SITDR, output of the sync signal resumes
when the value of T4 to T0 in SIFDR becomes H'01 or above.
