AT32UC3A3
25.7.3 Interrupt Enable Register
Name: IER
Access Type: Write-only
Offset: 0x08
Reset Value: 0x00000000
Writing a zero to a bit in this register has no effect.
Writing a one to a bit in this register will set the corresponding bit in IMR.
• LINSNRE: LIN Slave Not Responding Error
• LINCE: LIN Checksum Error
• LINIPE: LIN Identifier Parity Error
• LINISFE: LIN Inconsistent Sync Field Error
• LINBE: LIN Bit Error
• MANEA/MANE: Manchester Error
• CTSIC: Clear to Send Input Change Flag
• DCDIC: Data Carrier Detect Input Change Flag
• DSRIC: Data Set Ready Input Change Flag
• RIIC: Ring Indicator Input Change Flag
• LINTC: LIN Transfer Completed
• LINIDR: LIN Identifier
• NACK: Non Acknowledge
• RXBUFF: Reception Buffer Full
• ITER/UNRE: Max number of Repetitions Reached or SPI Underrun Error
• TXEMPTY: Transmitter Empty
• TIMEOUT: Receiver Time-out
• PARE: Parity Error
• FRAME: Framing Error
• OVRE: Overrun Error
• RXBRK: Break Received/End of Break
• TXRDY: Transmitter Ready
• RXRDY: Receiver Ready
For backward compatibility the MANE bit has been duplicated to the MANEA bit position. Writing either one or the other has
the same effect. The corresponding bit in CSR and the corresponding interrupt request are named MANERR.
