23.10.10 UCSR1C – USART1 Control and Status Register C
364
ATmega128RFA1
The UCSZ12 bits combined with the UCSZ11:0 bit in UCSR1C sets the number of data
bits (Character Size) in the frame that the Receiver and Transmitter use.
• Bit 1 – RXB81 - Receive Data Bit 8
RXB81 is the 9th data bit of the received character when operating with serial frames
with nine data bits. The bit must be read before reading the lower 8 bits from UDR1.
• Bit 0 – TXB81 - Transmit Data Bit 8
TXB81 is the 9th data bit in the character to be transmitted when operating with serial
frames with nine data bits. The bit must be written before writing the lower 8 bits to
UDR1.
• Bit 7:6 – UMSEL11:10 - USART Mode Select
These bits select the mode of operation of the USART1 as shown in the following table.
See section "USART in SPI Mode" for a full description of the Master SPI Mode
(MSPIM) operation.
Table 23-9 UMSEL1 Register Bits
• Bit 5:4 – UPM11:10 - Parity Mode
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 UPM1 setting. If a mismatch is detected, the UPE1 Flag in UCSR1A
will be set.
Table 23-10 UPM1 Register Bits
• Bit 3 – USBS1 - Stop Bit Select
This bit selects the number of stop bits to be inserted by the Transmitter. The Receiver
ignores this setting.
