Advanced light control and diagnostics using
SPC56xBx and SPC56xCx microcontrollers
Introduction
The members of the SPC56xBx and SPC56xCx families are high performance
microcontrollers developed for car body application needs. These devices are especially
useful in automotive light management applications and offer features to assist the car body
system developer in writing optimized firmware with a very low CPU load.
This document offers an interesting example about the interconnection between the eMIOS,
CTU, and ADC modules of the SPC56EC74 (one member of the SPC56xB/Cx family) in a
lighting application, including the support of circuitry diagnostics, without placing an
additional load on the MCU’s CPU. This example is easily applied to each device of the
SPC56xB/Cx family.
