Initialization Request — Requesting initialization mode by setting this bit will place the SLIC module into its
initialized state immediately. As a result of setting INITREQ, INITACK will be set in SLCS. INITACK = 1 causes
all SLIC register bits (except SLCWCM: write once) to be held in their reset states and become not writable until
INITACK has been cleared. If transmission or reception of data is in progress, the transaction will be terminated
immediately upon entry into initialization mode (signified by INITACK being set to 1). To return to normal SLIC
operation after the SLIC has been initialized (the INITACK is high), the INITREQ must be cleared by software.
0 Normal operation
1 Request for SLIC to be put into reset state immediately
BEDD Bit Error Detection Disable — This bit allows the user to disable bit error detection circuitry. Bit error
detection monitors the received bits to determine if they match the state of the corresponding transmitted bits.
When bit error detection is enabled and a mismatch between transmitted bit and received bit is detected, a bit
error is reported to the user through the SLCSV register and a SLIC interrupt is generated (if SLIC interrupts are
enabled). The user must ensure that all physical delays which affect the timing of received bits are not
significant enough to cause the bit error detection circuitry to incorrectly detect bit errors at higher LIN
bus speeds. See
0 Bit Error Detection Enabled
1 Bit Error Detection Disabled no bit errors will be detected or reported
Transmit Wakeup Symbol— This bit allows the user to transmit a wakeup symbol on the LIN bus. When set,
this sends a wakeup symbol, as defined in the LIN specification a single time, then resets to 0. This bit will read
1 while the wakeup symbol is being transmitted on the bus. This bit will be automatically cleared when the wakeup
symbol is complete.

Section 12.6.15, “Bit Error Detection and Physical Layer
Bit Error detection is not recommended for use in BTM mode,
as bit errors are reported on bit boundaries, not byte
boundaries. This can result in misaligned data.
Bit errors must not be disabled during normal LIN operations,
as it allows the SLIC module to operate outside of the LIN
specification. If you switch off bit error detection, there is no
guaranteed way to detect bus collisions and automatically
cease transmissions. Therefore pending SLIC transmissions
may continue after a bit error should have been detected,
potentially corrupting bus traffic.
