An illumination interface is provided that supports up to a 3-channel LED driver.
The illumination interface provides signals that support LED driver enable, LED enable, LED enable select, and PWM signals to control the LED current. Table 12 describes the active signals for the illumination interface.
|HEARTBEAT||LED blinks continuously to indicate system is running fine|
|FAULT_STATUS||LED off indicates system fault|
|LEDR_EN||Red LED enable|
|LEDG_EN||Green LED enable|
|LEDB_EN||Blue LED enable|
|LEDR_PWM||Red LED PWM signal used to control the LED current|
|LEDG_PWM||Green LED PWM signal used to control the LED current|
|LEDB_PWM||Blue LED PWM signal used to control the LED current|
