LIN System Clock Requirements
The LIN master provides the timing reference for the LIN network and is required to have
a clock source with a tolerance of ±0.5%. A slave with autobaud capability is required to
have a baud clock matching the master oscillator within ±14%. The slave nodes autobaud
to lock onto the master timing reference with an accuracy of ±2%. If a slave does not con-
tain autobaud capability, it must include a baud clock which deviates from the masters by
no more than ±1.5%. These accuracy requirements must include effects such as voltage
and temperature drift during operation.
Before sending or receiving messages, the baud reload High/Low registers must be initial-
ized. Unlike standard UART modes, the baud reload High/Low registers must be loaded
with the baud interval rather than 1/16 of the baud interval.
To autobaud with the required accuracy, the LIN slave system clock must be at least 100
times the baud rate.
LIN Mode Initialization and Operation
The LIN protocol mode is selected by setting either the LIN master (
(
register. To access the LIN control register, the mode select (MSEL) field of the LIN-
UART mode select/status register must be
be initialized with TEN = 1, REN = 1, all other bits = 0.
In addition to the LMST, LSLV and ABEN bits in the LIN control register, a LinState[1:0]
field exists that defines the current state of the LIN logic. This field is initially set by the
LSLV
Parity error (PE bit in Status0 register) is redefined as the Physical Layer Error (PLE)
bit. The PLE bit indicates that receive data does not match transmit data when the LIN-
UART is transmitting. This applies to both MASTER and SLAVE OPERATING
modes.
The break detect interrupt (
tected by the slave (break condition for at least 11 bit times). Software uses this inter-
rupt to start a timer checking for message frame timeout. The duration of the break is
