The identification of errors is triggered in one of two ways.

1) Busy or

2) Device failure to respond to IIC. In the event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with continuous flashing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device number will be displayed through the LED (Series of flashes which must be counted) , non fatal errors are reported using this method.

ERROR DETECTION MONITOR

Device acknowledges is used to check IIC errors.  Each device is checked three times, if there is no acknowledge after every attempt, it will be regarded as an error.  There are three step to check errors.

IIC line 0:  If all devices except the NVM have errors, IIC line 0 errors are displayed.
Each device check:  if IIC line error and board error are not detected then the device with an error is displayed.

The detected errors can be displayed as follows:
1)  Error Monitor Menu
2)  Error Reader

Error Monitor Menu
The error monitor menu is displayed by selecting Service mode : Monitoring. The following menu will be displayed.
