• Manufacturer Part Number: HD6413008F
• Description: Renesas 16-Bit Single-Chip Microcomputer H8 Family/H8/300H Series
• Manufacturer: RENESAS [Renesas Technology Corp]

Asynchronous Mode
• Data length is selectable: 7 or 8 bits
• Parity and multiprocessor bits are selectable, and so is the stop bit length (1 or 2 bits). These
• In receiving, it is possible to detect framing errors, parity errors, overrun errors, and the break
• An internal or external clock can be selected as the SCI clock source.
Synchronous Mode
• The communication format has a fixed 8-bit data length.
• In receiving, it is possible to detect overrun errors.
• An internal or external clock can be selected as the SCI clock source.
Smart Card Interface
• One frame consists of 8-bit data and a parity bit.
• In transmitting, a guard time of at least two elementary time units (2 etu) is provided between
• In receiving, if a parity error is detected, a low error signal level is output for 1 etu, beginning
• In transmitting, if an error signal is received, the same data is automatically transmitted again
• Only asynchronous communication is supported. There is no synchronous communication
selections determine the communication format and character length.

⎯ When an internal clock is selected, the SCI operates using the on-chip baud rate generator,
⎯ When an external clock is selected, the external clock input must have a frequency 16 times
⎯ When an internal clock is selected, the SCI operates using the on-chip baud rate generator,
