Note 1: The transmit is started with overflow timing of BRG after having written in a value at the transmit buffer in the above timing.
Note 2: TxD
The above timing applies to the following settings :
Shown in ( ) are bit symbols.
• Parity is enabled.
• One stop bit.
• Transmit interrupt cause select bit = “1”.
