If the CPU is in STOP mode, the LIN-UART is not active and the Wake-up message must
be detected by a GPIO edge detect Stop Mode Recovery. The duration of the Stop Mode
Recovery sequence may preclude making an accurate measurement of the Wake-up
message duration.
If the CPU is in HALT or operational mode, the LIN-UART (if enabled) times the duration
of the Wake-up and provides an interrupt following the end of the break sequence if the
duration is  3 bit times. The total duration of the Wake-up message in bit times may be
obtained by reading the
up message has been detected, the LIN-UART can be placed (by software) into either LIN
Master or LIN Slave Wait for Break states as appropriate. If the break duration exceeds 15
bit times, the
the Wake-up message can be detected via a port pin interrupt and timed by software. If the
device is in STOP mode, the High to Low transition on the port pin bring the device out of
STOP mode.
The LIN Sleep state is selected by software setting
move from an active state to sleep state is based on the LIN messages as interpreted by
software.
LIN Slave Operation
LIN Slave mode is selected by setting
LinState[1:0]
message by the Break which appears to the Slave as a break of at least 11 bit times in
duration. The LIN-UART detects the Break and generates an interrupt to the CPU. The
duration of the Break is observable in the
register. A Break of less than 11 bit times in duration does not generate a break interrupt
when the LIN-UART is in Wait for Break state. If the Break duration exceeds 15 bit times,
the
Following the Break the LIN-UART hardware automatically transits to the Autobaud
state, where it autobauds by timing the duration of the first 8 bit times of the Synch
character as defined in the standard. At the end of the autobaud period, the duration
measured by the BRG counter (auto baud period divided by 8) is automatically transferred
to the Baud Reload High and Low registers if the
set. If the BRG Counter overflows before reaching the start of bit 7 in the autobaud
sequence the Autobaud Overrun Error interrupt occurs, the
set and the Baud Reload registers are not updated. To autobaud within 2% of the master’s
baud rate, the slave system clock must be minimum 100 times the baud rate. To avoid an
autobaud overrun error, the system clock must not be greater than 2
(16 bit counter following 3-bit prescaler when counting the 8 bit times of the Autobaud
sequence).
Following the Synch character, the LIN-UART hardware transits to the Active state where
the Identifier character is received and the characters of the Response section of the
message are sent or received. The Slave remains in the Active state until a Break is
