Description
Reserved
These read-only bits are reserved for future use
LHS Reset Complete Flag
This bit is set to 1 by hardware to indicate a LHS Reset Command has completed successfully.
This bit is cleared to 0, after user code reads the LHSSTA MMR
Break Field Error
This bit is set to 1 by hardware and generates an LHS Interrupt (IRQEN[7]) when the 12-bit, Break Timer (LHSVAL1) register
overflows to indicate the LIN bus has stayed low too long thus indicating a possible LIN bus error.
This bit is cleared to 0, after user code reads the LHSSTA MMR
LHS Compare Interrupt
This bit is set to 1 by hardware when the value in LHSVAL0 (LIN Synchronisation Bit Timer) = the value in the LHSCMP
register.
This bit is cleared to 0, after user code reads the LHSSTA MMR
Stop Condition Interrupt
This bit is set to 1 by hardware when a stop condition is detected.
This bit is cleared to 0, after user code reads LHSSTA MMR
Start Condition Interrupt
This bit is set to 1 by hardware when a start condition is detected.
This bit is cleared to 0, after user code reads LHSSTA MMR
Break Timer Compare Interrupt
This bit is set to 1 by hardware when a valid LIN Break condition is detected. A LIN Break conditions is generated when
the LIN Break Timer value reaches the Break timer compare value (see LHSVAL1 description below).
This bit is cleared to 0, after user code reads the LHSSTA MMR

Read Only
The LHS Status register is an 8-bit register whose bits reflect the current operating status of the ADuC7032 LIN
interface.
