Specifications REV. G
Specifications in this manual are tentative and subject to change
UART0 to UART2
1.2.23.2 Clock asynchronous serial I/O (UART) mode
The UART mode allows transmitting and receiving data after setting the desired transfer rate and
transfer data format. Table 1.27 lists the specifications of the UART mode.
Table 1.27:
Specifications of UART mode
Note 1: ‘n’ denotes the value 0016 to FF16 that is set to the UARTi bit rate generator.
Note 2: fEXT is input from the CLKi pin. External clock cannot be selected in UART2.
Note 3: If an overrun error occurs, the UARTi receive buffer will have the next data written in. Note also that the UARTi receive interrupt
request bit is not set to “1”
Item
Specification
Transfer data format
Character bit (transfer data): 7 bits, 8 bits, or 9 bits as selected
Start bit: 1 bit
Parity bit: Odd, even, or nothing as selected
Stop bit: 1 bit or 2 bits as selected
Transfer clock
When internal clock is selected (bit 3 at addresses 03A016, 03A816, 037816 = “0”):
fi/16(n+1) (Note 1) fi = f1, f8, f32
When external clock is selected (bit 3 at addresses 03A016, 03A816=“1”):
fEXT/16(n+1)(Note 1) (Note 2)
Transmission/reception
control
CTS function/RTS function/ CTS, RTS function disabled
Transmission start condition
To start transmission, the following requirements must be met:
Transmit enable bit (bit 0 at addresses 03A516, 03AD16, 037D16) = “1”
Transmit buffer empty flag (bit 1 at addresses 03A516, 03AD16, 037D16) = “0”
When CTS function selected, CTS input level = “L”
Reception start condition
To start reception, the following requirements must be met:
Receive enable bit (bit 2 at addresses 03A516, 03AD16, 037D16) = “1”
Start bit detection
Interrupt request generation
timing
When transmitting
Transmit interrupt cause select bits (bits 0,1 at address 03B016, bit4 at address 037D16) = “0”:
Interrupts requested when data transfer from UARTi transfer buffer register to UARTi transmit
register is completed
Transmit interrupt cause select bits (bits 0, 1 at address 03B016, bit4 at address 037D16) = “1”:
Interrupts requested when data transmission from UARTi transfer register is completed
When receiving
Interrupts requested when data transfer from UARTi receive register to UARTi receive buffer
register is completed
Error detection
Overrun error (Note 3)
This error occurs when the next data is ready before contents of UARTi receive buffer register are
read out
Framing error
This error occurs when the number of stop bits set is not detected
Parity error
This error occurs when if parity is enabled, the number of 1’s in parity and character bits does not
match the number of 1’s set
Error sum flag
This flag is set (= 1) when any of the overrun, framing, and parity errors is encountered
Select function
Sleep mode selection (UART0, UART1)
This mode is used to transfer data to and from one of multiple slave micro-computers
Serial data logic switch (UART2)
This function is reversing logic value of transferring data. Start bit, parity bit and stop bit are not
reversed.
TxD, RxD I/O polarity switch (UART2)
This function is reversing TxD port output and RxD port input. All I/O data level is reversed.
