LMST—LIN Master Mode
0 = LIN Master mode not selected.
1 = LIN Master mode selected (if
= 0)
MPEN, PEN, LSLV
LSLV—LIN Slave Mode
0 = LIN Slave mode not selected.
1 = LIN Slave mode selected (if
= 0)
MPEN, PEN, LMST
ABEN—Autobaud Enable
0 = Autobaud not enabled.
1 = Autobaud enabled if in LIN SLAVE mode.
ABIEN—Autobaud Interrupt Enable
0 = Interrupt following autobaud does not occur.
1 = Interrupt following autobaud enabled if in LIN SLAVE mode. When the autobaud
character is received, a receive interrupt is generated and the
bit is set in the status0
ATB
register.
LinState[1:0]—LIN State Machine
The LinState is controlled by both hardware and software. Software 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 state from Sleep to Active where it remains until
software sets it back to the Sleep state. After configuration software does not alter the
field during operation.
LinState
00 = Sleep State (either LMST or LSLV is 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 is 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
