12.3.4   

Transmit Operation 

Transmission is started by setting the UnIO bit of the UARTn mode register 0 (UA0MOD0) to “0” to select transmit mode 
and setting the UnEN bit of the UARTn control register (UAnCON) to “1”. 
Figure 12-5 shows the operation timing for transmission. 

 

When the UnEN bit is set to “1” (

), the baud rate generator generates an internal transfer clock of the baud rate set and 

starts transmission. 
The start bit is output to the TXDn pin by the falling edge of the internal transfer clock (

). Subsequently, the transmitted 

data, a parity bit, and a stop bit are output. 
When the start bit is output (

), a UARTn interrupt is requested. In the UARTn interrupt routine, the next data to be 

transmitted is written to the transmit/receive buffer (UAnBUF). 
When the next data to be transmitted is written to the transmit/receive buffer (UAnBUF), the transmit buffer status flag 
(UnFUL) is set to “1” (

) and a UARTn interrupt is requested on the falling edge of the internal transfer clock (

) after 

transmission of the stop bit. If the UARTn interrupt routine is terminated without writing the next data to the 
transmit/receive buffer, the UnFUL bit is not set to “1” (

) and transmission continues up to the transmission of the stop 

bit, then the UnEN bit is reset to “0” and a UARTn interrupt is requested. 
The valid period for the next transmit data to be written to the transmit/receive buffer is from the generation of an interrupt 
to the termination of stop bit transmission. (
