Figure 1.16.18. Typical transmit timings in UART mode(UART2)
• Example of transmit timing when transfer data is 8 bits long (parity enabled, one stop bit)
Transmit interrupt
request bit (IR)
Transfer clock
Transmit enable

Transmit buffer
empty flag(TI)
TxD
Transmit register
empty flag (TXEPT)
Note: The transmit is started with overflow timing of BRG after having written in a value at the transmit buffer in the above timing.

Shown in ( ) are bit symbols.
The above timing applies to the following settings :
• Parity is enabled.
• One stop bit.
• Transmit interrupt cause select bit = “1”.
