Figure 21. LIN Interface
Slave Operational Range for Proper Self
Synchronization
The LIN interface will synchronize properly in the
following conditions:
? Vbat w 8 V V BB w 7.3 V
? Ground shift between master node and slave node <
± 1 V
It is highly recommended to use the same type of reverse
battery voltage protection diode for the Master and the Slave
nodes.
Functional Description
Analog Part
The transmitter is a low ? side driver with a pull ? up resistor
and slope control. The receiver mainly consists of a
comparator with a threshold equal to V BB /2. Figure 5 shows
Table 24. LIN ERROR REGISTER
the characteristics of the transmitted and received signal.
See AC Parameters for timing values.
Protocol Handler
This block implements:
? Bit Synchronization
? Bit Timing
? The MAC Layer
? The LLC Layer
? The Supervisor
Error Status Register
The LIN interface implements a register containing an
error status of the LIN communication. This register is as
follows:
Bit 7
Not used
Bit 6
Not used
Bit 5
Not used
Bit 4
Not used
Bit 3
Time out
error
Bit 2
Data error
Flag
Bit 1
Header error
Flag
Bit 0
Bit error Flag
With:
? Time out error: The message frame is not fully
completed within the maximum length T FRAME_MAX
? Data error flag: Checksum error ⊕ StopBit error ⊕
Length error
? Header error flag:Parity ⊕ SynchField error
? Bit error flag: Difference in bit sent and bit monitored
on the LIN bus
A GetFullStatus frame will reset the error status
register.
