bits of the data read from the UDR will be masked to zero. The USART has to be initialized
before the function can be used.
Note:
The function simply waits for data to be present in the receive buffer by checking the RXC Flag,
before reading the buffer and returning the value.
Receiving Frames with
9 Data Bits
If 9-bit characters are used (UCSZ=7) the ninth bit must be read from the RXB8 bit in 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.
Assembly Code Example
USART_Receive:
; Wait for data to be received
sbis
UCSRA, RXC
rjmp
USART_Receive
; Get and return received data from buffer
in
r16, UDR
ret
C Code Example(1)
unsigned char
USART_Receive( void )
{
/* Wait for data to be received */
while
( !(UCSRA & (1<<RXC)) )
;
/* Get and return received data from buffer */
return
UDR;
}
