Initial Value
Read/Write
• Bit 2 – UCSZn2: Character Size n
• Bit 1 – RXB8n: Receive Data Bit 8 n
• Bit 0 – TXB8n: Transmit Data Bit 8 n
• Bits 7:6 – UMSELn1:0 USART Mode Select
• Bits 5:4 – UPMn1:0: Parity Mode
• Bit 3 – USBSn: Stop Bit Select
The UCSZn2 bits combined with the UCSZn1:0 bit in UCSRnC sets the number of data
bits (Character SiZe) in a frame the Receiver and Transmitter use.
RXB8n is the ninth data bit of the received character when operating with serial frames
with nine data bits. Must be read before reading the low bits from UDRn.
TXB8n is the ninth data bit in the character to be transmitted when operating with serial
frames with nine data bits. Must be written before writing the low bits to UDRn.
These bits select the mode of operation of the USARTn as shown in
These bits enable and set type of parity generation and check. If enabled, the Transmitter
will automatically generate and send the parity of the transmitted data bits within each
frame. The Receiver will generate a parity value for the incoming data and compare it to
the UPMn setting. If a mismatch is detected, the UPEn Flag in UCSRnA will be set.
This bit selects the number of stop bits to be inserted by the Transmitter. The Receiver
ignores this setting.
