46 / 68 page  MIC3000 Micrel M9999-101204 46 October 2004 Received Optical Power MSB (RXOPh) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read-only read-only read-only read-only read-only read-only read-only read-only Default Value 0000 0000b = 00h (0mW)(6) Serial Address A2h = 1010001b Byte Address 104 = 68h Each LSB represents 25.6 µW. This register is to be used in conjunction with RXOPl to yield a sixteen-bit value. The values in RXOPh:RXOPl are in an unsigned binary format. The value in this register is uncalibrated. The host should process the results using the scale factor and offset provided. See the External Calibration section. Received Optical Power LSB (RXOPl) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read-only read-only read-only read-only read-only read-only read-only read-only Default Value 0000 0000b = 00h (0mW)(6) Serial Address A2h = 1010001b Byte Address 105 = 69h Each LSB represents 0.1 µW. This register is to be used in conjunction with RXOPh to yield a sixteen-bit value. The values in RXOPh:RXOPl are in an unsigned binary format. The value in this register is uncalibrated. The host should process the results using the coefficients provided. See the External Calibration section. In the MIC3000, this register will always return zero. This register is provided for compliance with SFF-8472. It is not used by the MIC3000 when doing threshold comparisons and setting alarm or warning bits. Control and Status (CNTRL) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] TXDIS STXDIS reserved RSEL SRSEL XFLT LOS POR read only read/write read/write read/write read only read only read only Default Value 0000 0000b = 00h Serial Address A2h = 1010001b Byte Address 110 = 6Eh Bit(s) Function Operation D[7] TXDIS Reflects the state of the TXDISABLE pin 1 = disabled, 0 = enabled, read only. D[6] STXDIS Soft transmit disable 1 = disabled; 0 = enabled. D[5] D[5] Reserved Reserved - always write as zero. D[4] RSEL Reflects the state of the RSEL pin 1 = high; 0 = low. D[3] SRSEL Soft rate select 1 = high (2Gbps); 0 = low (1Gbps). D[2] TXFLT Reflects the state of the TXFAULT pin 1 = high (fault); 0 = low (no fault). D[1] LOS Loss of signal. Reflects the state of the LOS pin 1 = high (loss of signal); 0 = low (no loss of signal). D[0] POR MIC3000 power-on status 0 = POR complete, analog data ready; 1 = POR in progress. Notes: 6. RXOPh will contain measured data after one A/D conversion cycle. |
