Section 16 Serial Communication Interface with FIFO (SCIF)
16.2.6
The SCSCR2 register performs enabling or disabling of SCIF transfer operations, and interrupt
requests, and selection of the serial clock source.
SCSCR2 can be read or written to by the CPU at all times.
SCSCR2 is initialized to H'0000 by a power-on reset or manual reset. It is not initialized in
standby mode or in the module standby state.
Bits 15 to 8, 2, and 0—Reserved: These bits are always read as 0, and should only be written
with 0.
Bit 7—Transmit Interrupt Enable (TIE): Enables or disables transmit-FIFO-data-empty
interrupt (TXI) request generation when serial transmit data is transferred from SCFTDR2 to
SCTSR2, the number of data bytes in the transmit FIFO register falls to or below the transmit
trigger set number, and the TDFE flag in the serial status register (SCFSR2) is set to 1.

Serial Control Register (SCSCR2)
TXI interrupt requests can be cleared by writing transmit data exceeding the transmit
trigger set number to SCFTDR2 after reading 1 from the TDFE flag, then clearing it to 0,
or by clearing the TIE bit to 0.
