Section 13 Serial Communication Interface (SCI)
Transmit/Receive Formats: Table 13.10 shows the 12 communication formats that can be
selected in asynchronous mode. The format is selected by settings in the serial mode register
(SMR).
Table 13.10 Serial Communication Formats (Asynchronous Mode)
—: Don’t care bits.
Notes: START: Start bit
Clock: An internal clock generated by the on-chip baud rate generator or an external clock input
from the SCK pin can be selected as the SCI transmit/receive clock. The clock source is selected
by the C/A bit in the serial mode register (SMR) and bits CKE1 and CKE0 in the serial control
register (SCR) (table 13.9).
When an external clock is input at the SCK pin, it must have a frequency equal to 16 times the
desired bit rate.
