21. Serial Communication Interface with FIFO (SCIF)
Clocked Synchronous Mode
• Data length: Fixed at 8 bits
• LSB first for data transmission and reception
• Detection of overrun errors during reception
• Choice of peripheral clock (Pck) or SCIF_SCK pin input as SCIF clock source
When peripheral clock (Pck) is selected: The SCIF operates on the baud rate generator clock
and a serial clock is output to external devices.
When SCIF_SCK pin input is selected: The on-chip baud rate generator is not used and the
SCIF operates on the input serial clock.
