Section 16 Serial Communication Interface with FIFO (SCIF)
16.4
16.4.1
For serial communication, the SCIF has an asynchronous mode in which characters are
synchronized individually, and a clocked synchronous mode in which communication is
synchronized with clock pulses.
The SCIF has a 16-stage FIFO buffer for both transmission and receptions, reducing the overhead
of the CPU, and enabling continuous high-speed communication. The transmission format is
selected in the serial mode register (SCSMR), as shown in table 16.9. The SCIF clock source is
selected by the combination of the CKE1 and CKE0 bits in the serial control register (SCSCR), as
shown in table 16.10.
(1)
• Data length is selectable: 7 or 8 bits
• Parity bit is selectable. So is the stop bit length (1 or 2 bits). The combination of the preceding
• In receiving, it is possible to detect framing errors, parity errors, receive FIFO data full,
• The number of stored data bytes is indicated for both the transmit and receive FIFO registers.
• An internal or external clock can be selected as the SCIF clock source.
(2)
• The transmission/reception format has a fixed 8-bit data length.
• In receiving, it is possible to detect overrun errors (ORER).
• An internal or external clock can be selected as the SCIF clock source.
