CHAPTER 13 UART

UART interrupt sources

[Reception]

When data with the specified length is correctly received or when the overrun error or framing error occurs while data is being received, the reception interrupt request (IRQ6) is generated if the reception interrupt request is enabled (SSD: RIE = 1).

[Transmission]

When data to be transmitted is written into the SODR register, sent to the internal shift register, and the next data then becomes writable, the transmission interrupt request (IRQ5) is generated if the transmission interrupt request is allowed (SSD: TIE = 1).

UART prescaler, baud rate generator, clock divider selection register

The clock input to the baud rate generator is changeable by switching the rate of division using the clock divider selection registers.
