ERROR DETECTION MONITOR
Device acknowledge is used to check IIC errors. Device acknowledge is checked by sending an IIC start sequence during CRT power on. Each
device is checked three times, if there is no acknowledge after every attempt, it will be regarded as an error.
There are three steps to check errors
1. IIC line 0
If all devices except the NVM are errors, IIC line 0 error is displayed
2. Board check
If all devices mounted on one board have errors, board error is displayed
3. 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
