Description
8:9 BREAK_DELIMITER_LEN
GTH
RW R 1 In LIN mode, this field specifies the break delimiter
length:
(used in header transmission, not used in header
reception).
'0': 1 bit period.
'1': 2 bit periods (default value).
'2': 3 bit periods.
'3': 4 bit periods.
In UART mode, this field specifies the data field size:
'0': 5 bit data field.
'1': 6 bit data field.
'2': 7 bit data field.
'3': 8 bit data field.
When the data field size is less than 8 bits, the most
significant (unused) bits of the DATAx.DATAy[7:0]
fields should be set to '0' for the transmitter.
16:20 BREAK_WAKEUP
_LENGTH
RW R 12 Break/wakeup length (minus 1) in bit periods:
'0': 1 bit period.
...
'10': 11 bit periods (break length for slave nodes)
...
'12': 13 bit periods (break length for master nodes)
...
'30': 31 bit periods.
'31': Illegal (should NOT be used!!!)
This field is used for transmission/reception of BOTH
break and wakeup signals. Note that these functions
are mutually exclusive:
- When CMD.TX_HEADER is '1', the field specifies the
transmitted break field.
- When CMD.TX_WAKEUP is '1', the field specifies the
transmitted wakeup field.
- When CMD.RX_HEADER is '1', the field specifies the
to be received break field.
- Otherwise, the field specifies the to be received
wakeup field.
Per the standard, the master wakeup duration is
between 250 us and 5 ms. To support uncalibrated
slaves, a slave has a detection threshold of 150 us (3
bit periods at 20 kbps). After transmission of a break or
wakeup signal, the
INTR.TX_BREAK_WAKEUP_DONE interrupt cause is
activated. After reception of a wakeup signal, the
INTR.RX_BREAK_WAKEUP_DONE interrupt cause is
activated.
To specify longer wakeup signals in terms of absolute
time (us/ms rather than bit periods), the associated
PERI clock divider value can be (temporarily)
increased to make the LIN bit period longer.
Note: entering bus sleep mode is achieved with the
'go-to-sleep' command.
24 MODE RW R 0 Mode of operation:
'0': LIN mode.
'1': UART mode.
LIN 0 LIN mode.
UART 1 UART mode.
