Section 16 Serial Communication Interface with FIFO (SCIF)
In serial reception, the SCIF operates as described below.
1. The SCIF monitors the transmission line, and if a 0 start bit is detected, performs internal
2. The received data is stored in SCRSR2 in LSB-to-MSB order.
3. The parity bit and stop bit are received.
4. If the RIE bit in SCSCR2 is set to 1 when the RDF or DR flag changes to 1, a receive-FIFO-

synchronization and starts reception.
After receiving these bits, the SCIF carries out the following checks.
a. Stop bit check: The SCIF checks whether the stop bit is 1. If there are two stop bits, only
b. The SCIF checks whether receive data can be transferred from the receive shift register
c. Break check: The SCIF checks that the BRK flag is 0, indicating that the break state is not
If all the above checks are passed, the receive data is stored in SCFRDR2.
Note: Reception is not suspended when a receive error occurs.
data-full interrupt (RXI) request is generated.
If the RIE bit in SCSCR2 is set to 1 when the ER flag changes to 1, a receive-error interrupt
(ERI) request is generated.
If the RIE bit in SCSCR2 is set to 1 when the BRK flag changes to 1, a break reception
