CHAPTER 13 UART

13.4.5Serial Output Data Register (SODR)

The serial output data register (SODR) sends out (transmits) serial data.

■Serial Output Data Register (SODR)

Figure 13.4-7shows the configuration of the serial output data register bits.

Figure 13.4-7 Serial Output Data Register (SODR)

Address		bit7	bit6	bit5	bit4	bit3	bit2	bit1	bit0	Initial value
002BH										XXXXXXXXB
002BH										XXXXXXXXB
		W	W	W	W	W	W	W	W
W	: Write only
X	: Undefined

When transmission is enabled, writing data to be transmitted into this register after reading the SSD register sends the data to be transmitted to the transmission shift register, converts it into the serial format, then outputs it from the serial data output pin (UO pin).

When the transmitted data is written into the SODR register, the transmitted data flag bit is cleared with "0". After the transmitted data is sent to the transmission shift register, the transmitted data flag bit is set to "1", the data transmitted next then becomes writable. At this time, if the transmission interrupt request is enabled, an interrupt is generated. Write the data transmitted next when a transmission interrupt occurs or while the transmitted data flag bit is "1".
