Writing Frames
the slave nodes by means of a writing frame. According to
the LIN specification, identifiers are to be used to determine
to <ID5>, conform LIN1.3 specification. <ID6> = <ID0> ⊗
<ID1> ⊗ <ID2> ⊗ <ID4> (even parity) and <ID7> =
NOT(<ID1> ⊗ <ID3> ⊗ <ID4> ⊗ <ID5>) (odd parity).

writing frame with a dynamically assigned
identifier. This type is dedicated to short writing
actions when the bus load can be an issue. They
are used to provide direct command to one
((<Broad> = ‘1’) or all the slave nodes
with an identifier dynamically assigned to an
application command, regardless of the
physical address of the circuit.

Physical address
a specific action. If a physical addressing is needed, then
some bits of the data field can be dedicated to this, as
illustrated in the example below.
for example use the reserved identifier 0x3C and take
advantage of the 8 byte data field to provide a physical
address, a command and the needed parameters for the
action, as illustrated in the example below.

(<Broad> = ‘0’). If <Broad> = ‘1’, the
physical address of the slave node is provided

DATA3 to DATA4 will contain the command
parameters, as shown below.
