Clock asynchronous serial I/O (UART) mode
UART mode allows transmitting and receiving data after setting the desired transfer rate and transfer data format. Table
1.46 lists the specifications of the UART mode.
Note 1: 'm' denotes the value 00
Note 2: fEXT is input from the CLKi pin.
Note 3: If an overrun error occurs, the value of the UiRB register will be indeterminate. The IR bit of

CTS function, RTS function, CTS/RTS function chosen to be invalid
This function reverses the logic of transferred data. Start bit, parity bit and stop bit are not
reversed.
This function reverses the TxD port output and RxD port input. All I/O data levels are
reversed.
Character bit (transfer data): 7 bits, 8 bits, or 9 bits as selected
Start bit: 1 bit
Parity bit: odd, even, or neither is selected
Stop bit: 1 bit or 2 bits as selected
When internal clock is selected (bit 3 at address 03A8
When external clock is selected (bit 3 at address 03A8
To start transmission, the following requirements must be met:
To start receive, the following conditions must be met:

-Transmit enable bit (bit 0 at addresses 03AD
-Transmit buffer empty flag (bit 1 at address 03AD
-When CTS function is selected CTS input level = "1"
-Receive enable bit (bit 2 at addresses 03AD
-Start bit detection
-Transmit interrupt cause select bits (bit 4 at address 03AD
"0": Interrupts requested when data transfer from UARTi transfer buffer register to UARTi
transmit register is complete.
-Transmit interrupt cause select bits (bit 4 at address 03AD
"1": Interrupts requested when data transmission from UARTi transfer register is complete.
-Interrupts requested when data transfer from UARTi receive register to UARTi receive
buffer register is complete.
This error occurs if the serial I/O starts receiving the next data and receives the 7th bit
This error occurs when the number of stop bits set is not detected
If parity is enabled this error occurs when the number of "1"s in parity and character bits
does not match the number of "1"s set
This flag is set (=1) when any overrun, framing, and parity error occurs
of the next data before reading the UiRB register.
