The MC9S12XHY family is an optimized, automotive, 16-bit microcontroller
product line focused on low-cost and high-performance. This family is
intended to bridge from low-end 16-bit microcontrollers, such as MC9S12HY
family, to high performance 32-bit solutions. The MC9S12XHY family is
targeted at the lower end of automotive instrument cluster applications, it
includes support for CAN and LIN/J2602 communication and delivers typical
cluster requirements such as stepper motor control with stepper stall
