is selected (the CHR9 bit in the UART Control Register, UCR is set), the TXB8 bit in
UCR is transferred to bit 9 in the Transmit shift register.
On the baud rate clock following the transfer operation to the shift register, the start bit is
shifted out on the TXD pin. Then follows the data, LSB first. When the stop bit has been
shifted out, the shift register is loaded if any new data has been written to the UDR dur-
ing the transmission. During loading, UDRE is set. If there is no new data in the UDR
register to send when the stop bit is shifted out, the UDRE flag will remain set until UDR
is written again. When no new data has been written and the stop bit has been present
on TXD for one bit length, the TX Complete flag (TXC) in USR is set.
The TXEN bit in UCR enables the UART Transmitter when set (one). When this bit is
cleared (zero), the PD1 pin can be used for general I/O. When TXEN is set, the UART
Transmitter will be connected to PD1, which is forced to be an output pin regardless of
the setting of the DDD1 bit in DDRD.
Data Reception
Figure 42 shows a block diagram of the UART Receiver.
Figure 42. UART Receiver
The receiver front-end logic samples the signal on the RXD pin at a frequency 16 times
the baud rate. While the line is idle, one single sample of logical “0” will be interpreted as
the falling edge of a start bit and the start bit detection sequence is initiated. Let sample
