66 / 75 page  Micrel, Inc. MIC3003 November 2009 66 M9999-111209-C hbwhelp@micrel.com or (408) 955-1690 OEM Configuration 3 (OEMCFG3) D[7] QGPOM read/write D[6] TXFPOL read/write D[5] GPOD read/write D[4] GPOM read/write D[3] GPOC read/write D[2] TXFINM read/write D[1] LOSDIS read/write D[0] INTCAL read/write Default value 0000 1000b = 08h Serial address A6h Byte address 19 = 13h This register is non-volatile and will be maintained through power and reset cycles. A valid OEM password is required for access to this register. Bit Function Operation D[7] QGPOM QGPO pin function select 0: GPO (general purpose output) 1: Reset output D[6] TXFPOL TXFIN active polarity select; a fault is indicated when TXFIN = TXFPOL 0 = The TXFIN input is active-low 1 = The TXFIN input is active-high This bit is ignored if TXFINM = 0 D[5] GPOD GPO output drive 0 = GPO output is open-drain 1 = GPO output is push-pull This bit is ignored if GPOM = 0 D[4] GPOM GPO/RRSOUT pin mode select 0 = RRSOUT output 1 = GPO output D[3] GPOC GPO output control 0 = Set the GPO pin low 1 = Set the GPO pin high This bit is ignored if GPOM = 0 D[2] TXFINM SHDN/TXFIN pin mode select 0 = SHDN output 1 = TXFIN input D[1] LOSDIS RXLOS comparator and output disable 0 = RXLOS fault enabled, and the RXLOS output is enabled for normal operation 1 = RXLOS fault disabled; also, the RXLOS output is disabled, and will remain low D[0] INTCAL Calibration mode select 0 = External calibration mode 1 = Internal calibration.(the MIC3003’s ALU applies slope and offset coefficients to the ALU results as necessary) BIAS DAC Setting (APCDAC) Current VBIAS Setting D[7] read-only D[6] read-only D[5] read-only D[4] read-only D[3] read-only D[2] read-only D[1] read-only D[0] read-only Default value 0000 0000b = 00h Serial address A6h Byte address 20 = 14h This register reflects (reads back) the value being sent to the BIAS DAC (APCSET0, APCSET1, or APCSET2 whichever is selected, with temperature compensation applied). A valid OEM password is required for access to this register. |
