3.2.2 LIN-bus
The LIN-bus is connected to the connector J1. The capacitor C1 filters
the bus and the signal is connected to the pin LIN (20) of the physical
layer. The physical layer is internally connected to the PT0/TXD pin of
the MCU chip. The PTE1/RXD pin 40 is connected to RxD pin 41
externally. The IRQB_SMOS pin 18 from the Power Die module and
IRQB_MCU pin 9 are used to initiate MCU interrupt from the Power Die
chip. In LIN Stepper Controller this is used for MCU wake up from the
sleep via wake-up. Therefore jumper JP1 must be connected for user
(standard operational) mode.
