• Manufacturer Part Number: HD64F7050
• Description: 32-Bit RISC Microcomputer SuperH RISC engine Family/
• Manufacturer: RENESAS [Renesas Technology Corp]

Transmit/Receive Formats: Table 13.10 shows the 12 communication formats that can be
selected in the 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.
Note: 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).
