LINInitialise
TTZ740
none
none
LIN driver timer setup causes output compare pins to toggle
which creates a conflict with the hardware design
LINWakeup
TTZ740
none
Initial hardware design used the UPL interface, which is
not compatible with the LIN protocol for bus wakeup, hence
a custom wakeup routine is required for the UPL interface
