This setting is available in EUSART mode only when data bits are level encoded (in Manchester
the parity checker and generator are not available).
Bit 3 – USBS: Stop Bit Select
This bit selects the number of stop bits to be inserted by the Transmitter. The Receiver ignores
this setting.
In EUSART mode, the USBS bit has the same behavior and the EUSB bit of the EUSART allows
to configure the number of stop bit for the receiver in this mode.
Bit 2:1 – UCSZ1:0: Character Size
The UCSZ1:0 bits combined with the UCSZ2 bit in UCSRB sets the number of data bits (Char-
acter SiZe) in a frame the Receiver and Transmitter use.
When the EUSART mode is set, these bits have no effect.
Bit 0 – UCPOL: Clock Polarity
This bit is used for synchronous mode only. Write this bit to zero when asynchronous mode is
used. The UCPOL bit sets the relationship between data output change and data input sample,
and the synchronous clock (XCK).
