EPV (EEPROM VERIFY FAIL, bit 15)--This bit indicates that the verify operation of an EEPROM
write failed. It is cleared when the AR is read.
OT (OVER TEMPERATURE, bit 14)--This bit indicates that ambient temperature of the module
has exceeded the high temperature threshold for a period of at least 10 seconds. It is cleared
when the temperature falls below the high temperature threshold.
UT (UNDER TEMPERATURE, bit 13)--This bit indicates that ambient temperature of the module
has dropped below the low temperature threshold for a period of at least 10 seconds. It is cleared
when the temperature falls below the high temperature threshold.
CFO (CONFIGURATION OVERFLOW, bit 12)--This bit indicates that user configuration
commands have been executed more than 50,000 times. This bit is not cleared when the
configuration command counter exceeds 50,000. This bit can only be cleared at the JDS
Uniphase factory.
