Initial Value
resets all LINERR bits.
written to zero when LINENIR is written.
– 1 = An error has occurred.
– 0 = No identifier,
– 1 = Slave task: Identifier present, master task: Tx Header complete.
– 0 = No Tx,
– 1 = Tx Response complete.
– 0 = No Rx
– 1 = Rx Response complete.
– 0 = Error interrupt masked,
– 1 = Error interrupt enabled.
– 0 = Identifier interrupt masked,
– 1 = Identifier interrupt enabled.
The user clears this bit by writing 1 in order to reset this interrupt. Resetting LERR also
In UART mode, this bit is also cleared by reading LINDAT.
This bit generates an interrupt if its respective enable bit - LENIDOK - is set in LINENIR.
The user clears this bit by writing 1, in order to reset this interrupt.
This bit generates an interrupt if its respective enable bit - LENTXOK - is set in LINENIR.
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.
This bit generates an interrupt if its respective enable bit - LENRXOK - is set in LINENIR.
The user clears this bit by writing 1, in order to reset this interrupt.
