INSTRUCTIONS
This section describes how to use the
SJA1124 evaluation board as a hardware
plug-in board (shield) that supports up to
16 LIN master connections when plugged
on existing microcontroller development
boards.
The supply connector pin mapping of
J3 Header must be checked against
microcontroller board supply
connector. VBAT is the power supply
voltage (max 16V). VDD (3.3V / 5V),
P3V3 (3.3V) and P5V0 (5V) are
reference voltages. Otherwise
SJA1124 and other components on
the boards can be damaged.
