SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
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. Tables 1.37 and 1.38 list the specifications of the UART mode. Figure 1.93 shows the
UARTi transmit/receive mode register.
Table 1.37. Specifications of UART Mode (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 none 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)
CTS function/RTS function/CTS, RTS function chosen to be invalid
To start transmission, the following requirements must be met:
- Transmit enable bit (bit 0 at addresses 03A5 16, 03AD16, 037D16) = “1”
- Tr ansmit buffer empty flag (bit 1 at addresses 03A516,03AD16,037D 16)= “0”
- When CTS function selected, CTS input level = “L”
Receive start condition
To start reception, the following requirements must be met:
- Receive enable bit (bit 2 at addresses 03A5 16, 03AD16, 037D16) = “1”
- Start bit detection
Interrupt request
When transmitting
generation timing
- 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 character is received 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
Note 1: ‘n’ denotes the value 00 16 to FF16 that is set to the UARTi bit rate generator.
Note 2: f EXT is input from the CLKi pin.
Note 3: If an overrun error occurs, the UARTi receive buffer will have the last or most recent data written to it.
Note also that UARTi receive interrupt requst bit is not set to "1"
