Method to prevent the BAT.LED from turning on
Is there any method to prevent the BAT.LED from turning on when LCPU is running without the battery installed?
- Category :
Answer
To prevent an LED from turning on when an error occurs, set 0 to the relevant factor number setting area (4 bits for each) in SD207 to SD209.
To disable the BAT.LED indication for battery errors, write a hexadecimal "00A0" to SD209. (The priority order of battery error is 9.)
