2.11.2 Clock synchronous serial I/O mode
Table 2.11.2 Specifications of clock synchronous serial I/O mode (1)
Interrupt request
generation timing
The clock synchronous serial I/O mode uses a transfer clock to transmit and receive data. Tables 2.11.2
and 2.11.3 list the specifications of the clock synchronous serial I/O mode. Figures 2.11.15 and 2.11.16
show the UARTi transmit/receive mode register in clock synchronous serial I/O mode.

• Transfer data length: 8 bits
• When internal clock is selected (bit 3 at addresses 03A0
• When external clock is selected (bit 3 at addresses 03A0
• CTS function/RTS function/CTS, RTS function chosen to be invalid
• To start transmission, the following requirements must be met:

Input from CLKi pin
CLKi input level = “H”
CLKi input level = “L”
met:
CLKi input level = “H”
= “0”: Interrupts requested when data transfer from UARTi transfer buffer register to
UARTi transmit register is completed
= “1”: Interrupts requested when data transmission from UARTi transfer register is
completed
receive buffer register is completed
This error occurs when the next data is ready before contents of UARTi receive
buffer register are read out
