LINSCI
SERIAL COMMUNICATION INTERFACE (LIN Mode) (cont’d)
11.5.10 LIN Mode Register Description
STATUS REGISTER (SCISR)
Read Only
Reset Value: 1100 0000 (C0h)
Bits 7:4 = Same function as in SCI mode, please
refer to Section 11.5.8 SCI Mode Register De-
Bit 3 = LHE LIN Header Error.
During LIN Header this bit signals three error
types:
– The LIN Synch Field is corrupted and the SCI is
blocked in LIN Synch State (LSF bit = 1).
– A timeout occurred during LIN Header reception
– An overrun error was detected on one of the
header field (see OR bit description in Section
An interrupt is generated if RIE = 1 in the SCICR2
register. If blocked in the LIN Synch State, the LSF
bit must first be reset (to exit LIN Synch Field state
and then to be able to clear LHE flag). Then it is
cleared by the following software sequence: An
access to the SCISR register followed by a read to
the SCIDR register.
0: No LIN Header error
1: LIN Header error detected
Note:
Apart from the LIN Header this bit signals an Over-
run Error as in SCI mode; see description in Sec-
Bit 2 = NF Noise flag
In LIN Master mode (LINE bit = 1 and LSLV bit = 0)
this bit has the same function as in SCI mode;
please refer to Section 11.5.8 SCI Mode Register
In LIN Slave mode (LINE bit = 1 and LSLV bit = 1)
this bit has no meaning.
Bit 1 = FE Framing error.
In LIN slave mode, this bit is set only when a real
framing error is detected (if the stop bit is dominant
(0) and at least one of the other bits is recessive
(1). It is not set when a break occurs, the LHDF bit
is used instead as a break flag (if the LHDM
bit = 0). It is cleared by a software sequence (an
access to the SCISR register followed by a read to
the SCIDR register).
0: No Framing error
1: Framing error detected
Bit 0 = PE Parity error.
This bit is set by hardware when a LIN parity error
occurs (if the PCE bit is set) in receiver mode. It is
cleared by a software sequence (a read to the sta-
tus register followed by an access to the SCIDR
data register). An interrupt is generated if PIE = 1
in the SCICR1 register.
0: No LIN parity error
1: LIN Parity error detected
CONTROL REGISTER 1 (SCICR1)
Read/Write
Reset Value: x000 0000 (x0h)
Bits 7:3 = Same function as in SCI mode; please
refer to Section 11.5.8 SCI Mode Register De-
Bit 2 = PCE Parity control enable.
This bit is set and cleared by software. It selects
the hardware parity control for LIN identifier parity
check.
0: Parity control disabled
1: Parity control enabled
When a parity error occurs, the PE bit in the
SCISR register is set.
Bit 1 = Reserved
Bit 0 = Same function as in SCI mode; please refer
