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 com-
mand counter exceeds 50,000. This bit can only be cleared at the JDS Uniphase factory.
