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.

Interrupts requested when data transfer from UARTi receive register to
fi/ 2(n+1) (Note 1)
Input from CLKi pin
also be met:
CLKi input level = “H”
CLKi input level = “L”
also be met:
CLKi input level = “H”
CLKi input level = “L”
address 037D
