Wake-up Request
(Peripheral) DMA
Controller
In this configuration, the DMAC transfers only the DATA. The Identifier must be read by the user
in the LIN Identifier register (US_LINIR). The LIN mode must be written by the user in the LIN
Mode register (US_LINMR).
The WRITE buffer contains the DATA if the USART sends the response (NACT=PUBLISH).

(NACT=SUBSCRIBE).
Any node in a sleeping LIN cluster may request a wake-up.
In the LIN 2.0 specification, the wakeup request is issued by forcing the bus to the dominant
state from 250 μs to 5 ms. For this, it is necessary to send the character 0xF0 in order to impose
5 successive dominant bits. Whatever the baud rate is, this character respects the specified
timings.
In the LIN 1.3 specification, the wakeup request should be generated with the character 0x80 in
order to impose 8 successive dominant bits.
• Baud rate min = 1 kbit/s -> Tbit = 1ms -> 5 Tbits = 5 ms
• Baud rate max = 20 kbit/s -> Tbi t= 50 μs -> 5 Tbits = 250 μs
