Stop Communication Processing Bit. (slave mode only)
This bit always reads as 0.
0: No effect.
1: Block the processing of LIN communications until the next SYNC BREAK signal.
Sleep Mode Bit. (slave mode only)
0: Wake the device after receiving a Wakeup interrupt.
1: Put the device into sleep mode after receiving a Sleep Mode frame or a bus idle
timeout.
Transmit / Receive Selection Bit.
0: Current frame is a receive operation.
1: Current frame is a transmit operation.
Data Acknowledge Bit. (slave mode only)
Set to 1 after handling a data request interrupt to acknowledge the transfer. The bit
will automatically be cleared to 0 by the LIN controller.
Reset Interrupt Bit.
This bit always reads as 0.
0: No effect.
1: Reset the LININT bit (LIN0ST.3).
Reset Error Bit.
This bit always reads as 0.
0: No effect.
1: Reset the error bits in LIN0ST and LIN0ERR.
Wakeup Request Bit.
Set to 1 to terminate sleep mode by sending a wakeup signal. The bit will automati-
cally be cleared to 0 by the LIN controller.
Start Request Bit. (master mode only)
1: Start a LIN transmission. This should be set only after loading the identifier, data
length and data buffer if necessary.
The bit is reset to 0 upon transmission completion or error detection.
