Transmitter and Receiver Flags and Interrupts
Disabling the Transmitter or Receiver
Note:
The RXCn, TXCn, and UDREn flags and corresponding interrupts in USART in MSPIM mode
are identical in function to the normal USART operation. However, the receiver error status
flags (FE, DOR, and PE) are not in use and is always read as zero.
The disabling of the transmitter or receiver in USART in MSPIM mode is identical in function to
the normal USART operation.
Assembly Code Example
C Code Example
USART_MSPIM_Transfer:
USART_MSPIM_Wait_RXCn:
unsigned char USART_Receive( void )
{
}
; Wait for empty transmit buffer
sbis UCSRnA, UDREn
rjmp USART_MSPIM_Transfer
; Put data (r16) into buffer, sends the data
out UDRn,r16
; Wait for data to be received
sbis UCSRnA, RXCn
rjmp USART_MSPIM_Wait_RXCn
; Get and return received data from buffer
in r16, UDRn
ret
/* Wait for empty transmit buffer */
while ( !( UCSRnA & (1<<UDREn)) );
/* Put data into buffer, sends the data */
UDRn = data;
/* Wait for data to be received */
while ( !(UCSRnA & (1<<RXCn)) );
/* Get and return received data from buffer */
return UDRn;
1. The example code assumes that the part specific header file is included. For I/O Registers
located in extended I/O map, "IN", "OUT", "SBIS", "SBIC", "CBI", and "SBI" instructions must
be replaced with instructions that allow access to extended I/O. Typically "LDS" and "STS"
combined with "SBRS", "SBRC", "SBR", and "CBR".
