Serial I/O is configured with five channels: UART0 to UART2, SI/O3 and SI/O4.
UARTi each have an exclusive timer to generate a transfer clock, so they operate independently of each
other.
Figure 14.1 shows the block diagram of UARTi. Figures 14.2 and 14.3 shows the block diagram of the
UARTi transmit/receive.
UARTi has the following modes:
• Clock synchronous serial I/O mode
• Clock asynchronous serial I/O mode (UART mode).
• Special mode 1 (I
• Special mode 2 : UART2
• Special mode 3 (Bus collision detection function, IEBus mode) : UART2
• Special mode 4 (SIM mode) : UART2
Figures 14.4 to 14.9 show the UARTi-related registers.
Refer to tables listing each mode for register setting.
