UART
(6) Input to the serial I/O and the direction register
(7) Pins related to the serial I/O
(e) Bus collision detection function
• Transmission WITH: CTS function, WITHOUT: other functions ............................................... P358
• Reception WITH: RTS function, WITHOUT: other functions .................................................... P362
• Transmission WITH: direct format ............................................................................................ P366
• Reception WITH: direct format ................................................................................................. P370
To input an external signal to the serial I/O, set the direction register of the relevant port to input.
• CTS
• RTS
• CLK
• RxD
• TxD
Since TxD
This function is to sample the output level of the TxD pin and the input level of the RxD pin at the
rising edge of the transfer clock; if their values are different, then an interrupt request occurs.
The following are examples in which functions (a) to (e) are chosen:
Also, the SIM interface is used by adding some extra settings in UART2's clock-asynchronous serial
I/O mode. Direct or inverse format is selected by connecting SIM card.
