ATmega16M1/32M1/64M1

The user clears this bit by writing 1 in order to reset this interrupt. Resetting LERR also

resets all LINERR bits.

In UART mode, this bit is also cleared by reading LINDAT.

• Bit 2 - LIDOK: Identifier Interrupt

This bit generates an interrupt if its respective enable bit - LENIDOK - is set in LINENIR.

– 0 = No identifier,

– 1 = Slave task: Identifier present, master task: Tx Header complete.

The user clears this bit by writing 1, in order to reset this interrupt.

• Bit 1 - LTXOK: Transmit Performed Interrupt

This bit generates an interrupt if its respective enable bit - LENTXOK - is set in LINENIR.

–0 = No Tx,

–1 = Tx Response complete.

The user clears this bit by writing 1, in order to reset this interrupt.

In UART mode, this bit is also cleared by writing LINDAT.

• Bit 0 - LRXOK: Receive Performed Interrupt

This bit generates an interrupt if its respective enable bit - LENRXOK - is set in LINENIR.

– 0 = No Rx

– 1 = Rx Response complete.

The user clears this bit by writing 1, in order to reset this interrupt.

In UART mode, this bit is also cleared by reading LINDAT.

21.6.3 LINENIR – LIN Enable Interrupt Register

• Bits 7:4 - Res: Reserved

These bits are reserved for future use. For compatibility with future devices, they must be

written to zero when LINENIR is written.

• Bit 3 - LENERR: Enable Error Interrupt

– 0 = Error interrupt masked,

– 1 = Error interrupt enabled.

• Bit 2 - LENIDOK: Enable Identifier Interrupt

– 0 = Identifier interrupt masked,

– 1 = Identifier interrupt enabled.

• Bit 1 - LENTXOK: Enable Transmit Performed Interrupt

– 0 = Transmit performed interrupt masked,
