ATmega8(L)

Receiving Frames with 9 Data If 9-bit characters are used (UCSZ=7) the ninth bit must be read from the RXB8 bit in

Bits

UCSRB before reading the low bits from the UDR. This rule applies to the FE, DOR and

PE Status Flags as well. Read status from UCSRA, then data from UDR. Reading the

UDR I/O location will change the state of the receive buffer FIFO and consequently the

TXB8, FE, DOR, and PE bits, which all are stored in the FIFO, will change.
