The following code example shows a simple EUSART receive function.
Note:
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”.
19.5.3
Receiving 17 Data Bit Frames
In this configuration the seventeenth bit shoud be read from the RXB8 bit register, the rest of the
most significant bits (9, 10, 11, 12, 13, 14, 15 and 16) should be read from the EUDR register,
before the low byte of the character is read from UDR.
19.5.4
Receive Complete Flag and Interrupt
The EUSART Receiver has the same USART flag that indicates the Receiver state.
See “Receive Complete Flag and Interrupt” in USART section.
19.5.5
Receiver Error Flags
When the EUSART is not configured in Manchester mode, the EUSART has the three same
errors flags as standard mode: Frame Error (FE), Data OverRun (DOR) and Parity Error (UPE).
All can be accessed by reading UCSRA. (See “Receiver Error Flags” in USART section).
When the EUSART is configured in Machester mode, the EUSART has two errors flags: Data
OverRun (DOR), and Manchester framing error (FEM bit of EUCSRC).
