Section 16 Serial Communication Interface with FIFO (SCIF)
In serial transmission, the SCIF operates as described below.
1. When data is written into SCFTDR, the SCIF transfers the data from SCFTDR to SCTSR and
2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive
3. The SCIF checks the SCFTDR transmit data at the timing for sending the stop bit. If data is

starts transmitting. Confirm that the TDFE flag in SCFSR is set to 1 before writing transmit
data to SCFTDR. The number of data bytes that can be written is at least 16 – (transmit trigger
set number).
transmit operations are performed until there is no transmit data left in SCFTDR. When the
number of transmit data bytes in SCFTDR falls to or below the transmit trigger number set in
SCFCR, the TDFE flag is set. If the TIE bit in SCSCR is set to 1 at this time, a transmit-FIFO-
data-empty interrupt (TXI) request is generated.
The serial transmit data is sent from the TxD pin in the following order.
A. Start bit: One 0-bit is output.
B. Transmit data: 8-bit or 7-bit data is output in LSB-first order.
C. Parity bit: One parity bit (even or odd parity) is output. (A format in which a parity bit is
D. Stop bit(s): One or two 1-bits (stop bits) are output.
E. Mark state: 1 is output continuously until the start bit that starts the next transmission is
present, the data is transferred from SCFTDR to SCTSR, the stop bit is sent, and then serial
transmission of the next frame is started.
If there is no transmit data, the TEND flag in SCFSR is set to 1, the stop bit is sent, and then
the line goes to the mark state in which 1 is output.
