Serial I/O
Serial I/O
Serial I/O is configured with five channels: UART0 to UART2, SI/O3 and SI/O4.
UARTi (i=0 to 2)
UARTi each have an exclusive timer to generate a transfer clock, so they operate independently of each
other.
Figure 1.13.1 shows the block diagram of UARTi. Figure 1.13.2 shows the block diagram of the UARTi
transmit/receive unit.
UARTi has the following modes:
⢠Clock synchronous serial I/O mode
⢠Clock asynchronous serial I/O mode (UART mode).
⢠Special mode 1 (I2C mode)
⢠Special mode 2
Figures 1.13.3 to 1.13.8 show the UARTi-related registers.
Refer to tables listing each mode for register setting.
