7.2 Block description
SERIAL I/O
7–8
(1) Transmit enable bit (bit 0)
(2) Transmit buffer empty flag (bit 1)
(3) Receive enable bit (bit 2)
(4) Receive complete flag (bit 3)
By setting this bit to “1,” UARTi enters the transmission enable state. By clearing this bit to “0” during
transmission, UARTi enters the transmission disable state after the transmission which is performed
at that time is completed.
This flag is set to “1” when data set in the UARTi transmit buffer register is transferred from the
UARTi transmit buffer register to the UARTi transmit register. This flag is cleared to “0” when data
is set in the UARTi transmit buffer register.
By setting this bit to “1,” UARTi enters the reception enable state. By clearing this bit to “0” during
reception, UARTi quits the reception then and enters the reception disable state.
This flag is set to “1” when data is ready in the UARTi receive register and that is transferred to the
UARTi receive buffer register (i.e., when reception is completed). This flag is cleared to “0” when the
low-order byte of the UARTi receive buffer register is read out or when the receive enable bit (bit 2)
is cleared to “0.”
