XFP Laser Control and Digital Diagnostic IC
B1h
? LUT VALUE ......................<R-Module/W-Module><Shadowed Nonvolatile><00> This register contains the
fetched LUT value that drives the MODSET current. It can be read or overwritten to
directly control the MODSET current (manual mode).
B2h
? LUT_CONF .......................<R-Module/W-Module><Shadowed Nonvolatile><03>
Bit 0: AEN. A high on AEN enables data placed in the LUT VALUE register to drive MODSET.
Bit 1: TEN. A high on TEN enables the LUT INDEX POINTER to fetch data from the LUT.
Bit 2: SEEB. A high on SEEB disables EEPROM writes of Shadowed EEPROM locations.
Bit 3: Reserved.
Bit 4: Reserved.
Bit 5: Reserved.
Bit 6: Reserved.
Bit 7: Reserved.
B4h
? DAC STATUS ...................<R-Module/W-Module><Status><xx0xxx00b>
Bit 0: Reserved.
Bit 1: Reserved.
Bit 2: QT HIGH BIAS Flag. This flag indicates that the current entering BIASSET is above the threshold.
Bit 3: QT HIGH TX-P Flag. This flag indicates that TX-P is above the threshold.
Bit 4: QT LOW TX-P Flag. This flag indicates that TX-P is below the threshold.
Bit 5: Reserved.
Bit 6: SHUTDOWN Flag. A high indicates that the DS1862 is in shutdown mode and that FETG is asserted.
Bit 7: SAFETY Flag. A high indicates that a safety fault (quick trip) has occurred.
B8h
? MOD_PW_CHNG .............<R-never/W-Module><Shadowed Nonvolatile><00h> This is the 32-bit location that
the DS1862 uses to compare with the PWE to grant module password access. A
Read result is always <FFh>.
Table 05h
80h
? DS60 SCALE ....................<R-all/W-Factory><Nonvolatile><Factory Trimmed> This unique 16-bit value sets
the SCALE register for use with a DS60 temperature sensor on AUX2MON.
82h
? LM50 SCALE ....................<R-all/W-Factory><Nonvolatile><Factory Trimmed> This unique 16-bit value sets
the SCALE register for use with a LM50 temperature sensor on AUX2MON.
87h
? V THRSET_VALUE ................<R-all/W-all><Shadowed Nonvolatile><80> This 8-bit value sets the voltage on the
signal conditioner voltage source, THRSET.
