2503Q–AVR–02/11
• Bit 5:4 – UPM1:0: 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 UPM0 setting.
If a mismatch is detected, the PE Flag in UCSRA will be set.
Table 64. UPM Bits Settings
• 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.
Table 65. USBS Bit Settings
• 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.
