41 / 68 page  October 2004 41 M9999-101204 MIC3000 Micrel TX Optical Power High Warning MSB (TXHIGHh) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read/write read/write read/write read/write read/write read/write read/write read/write Default Value 0000 0000b = 00h (0mW) Serial Address A2h = 1010001b Byte Address 28= 1Ch Each LSB represents 25.6 µW. This register is to be used in conjunction with TXHIGHl to yield a sixteen-bit value. The values in TXHIGHh:TXHIGHl are in an unsigned binary format. The value in this register is uncalibrated. The value in TXHIGHh is compared against TXOPh. Warning bit Wx is set if TXOPh > TXHIGHh. TX Optical Power High Warning LSB (TXHIGHl) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read/write read/write read/write read/write read/write read/write read/write read/write Default Value 0000 0000b = 00h (0mW) Serial Address A2h = 1010001b Byte Address 29= 1Dh Each LSB represents 0.1 µW. This register is to be used in conjunction with TXHIGHh to yield a sixteen-bit value. The values in TXHIGHh:TXHIGHl are in an unsigned binary format. The value in this register is uncalibrated. The value in TXHIGHh is compared against TXOPh. Warning bit Wx is set if TXOPh > TXHIGHh. Since TXOPl is always zero, it is recommended that this register always be programmed to 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 b. TX Optical Power Low Warning MSB (TLOWh) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read/write Default Value 0000 0000b = 00h (0mW) Serial Address A2h = 1010001b Byte Address 30 = 1Eh Each LSB represents 25.6 µW. This register is to be used in conjunction with TXLOWl to yield a sixteen-bit value. The values in TXLOWh:TLOWl are in an unsigned binary format. The value in this register is uncalibrated. The value in TXLOWh is compared against TXOPh. Warning bit Wx is set if TXOPh < TXLOWh. TX Optical Power Low Warning LSB (TLOWl) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read/write read/write read/write read/write read/write read/write read/write read/write Default Value 0000 0000b = 00h (0mW) Serial Address A2h = 1010001b Byte Address 31 = 1Fh Each LSB represents 0.1 µW. This register is to be used in conjunction with TXLOWh to yield a sixteen-bit value. The values in TXLOWh:TXLOWl are in an unsigned binary format. The value in this register is uncalibrated. The value in TXLOWh is compared against TXOPh. Warning bit Wx is set if TXOPh < TXLOWh. Since TXOPl is always zero, it is recommended that this register always be programmed to 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. |
