Value Description (Continued)
LIN State Machine
The LinState is controlled by both hardware and software. Software can force a state
change at any time if necessary. In normal operation, software moves the state in and
out of Sleep state. For a LIN slave, software changes the state from Sleep to Wait for
Break, after which hardware cycles through the Wait for Break, Autobaud and Active
states. Software changes the state from one of the active states to Sleep state, if the
LIN bus goes into Sleep mode. For a LIN master, software changes the state from
Sleep to Active, where it remains until the software sets it back to the Sleep state. After
configuration, software does not alter the LinState field during operation.
00 Sleep state (either LMST or LSLV can be set).
01 Wait for Break state (only valid for LSLV = 1).
10 Autobaud state (only valid for LSLV = 1).
11 Active state (either LMST or LSLV can be set).
TxBreakLength
Used in LIN mode by the master to control the duration of the transmitted break.
00 13 bit times.
01 14 bit times.
10 15 bit times.
11 16 bit times.
