16. Serial I/O
Serial I/O consists of five channels (UART0 to UART4).
Each UARTi (i=0 to 4) has an exclusive timer to generate the transfer clock and operates independently.
Figure 16.1 shows a UARTi block diagram.
UARTi supports 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
- Special mode 3 (Clock-divided synchronous function, GCI mode)
- Special mode 4 (Bus conflict detect function, IE mode)
- Special mode 5 (SIM mode)
Figures 16.2 to 16.9 show registers associated with UARTi.
Refer to the tables listing each mode for register and pin settings.
