Bit 7: FST[7]. When the V CCT supply voltage is below 2.3V, the POR circuitry reports a fault. Once the V CCT supply
voltage is above 2.75V, the POR resets all registers to their default values and the fault is cleared.
Bit 6: FST[6]. When the voltage at BMON is above V CC - 0.5V, a SOFT FAULT is reported.
Bit 4: FST[4]. When the voltage at BMAX goes above 1.3V, a HARD FAULT is reported.
Bit 3: FST[3]. When the common-mode voltage at V TOUT Q goes below V CC - 1.3V, a SOFT FAULT is reported.
Bit 2: FST[2]. When the voltage at V TOUT Q goes below V CC - 0.8V, a HARD FAULT is reported.
Bit 1: FST[1]. When the BIAS voltage goes below 0.44V, a HARD FAULT is reported.
Bit 0: TX_FAULT. Copy of a FAULT signal in FST[7:6] and FST[4:1]. A POR resets the FST bits to 0.

Bit 3: IMODERR. Any attempt to modify SET_IMOD[8:1] above IMODMAX[7:0] flags a warning at IMODERR. (See the
Programming Modulation Current section.)
Bit 2: IBIASERR. Any attempt to modify SET_IBIAS[8:1] above IBIASMAX[7:0] flags a warning at IBIASERR. (See the
Programming Bias Current section.)
Bit 1: TXED. This indicates the absence of an AC signal at the transmit input.

Bits 7 to 0: SET_IBIAS[8:1]. The bias current DAC is controlled by a total of 9 bits. The SET_IBIAS[8:1] bits are used
to set the bias current with even denominations from 0 to 510 bits. The LSB (SET_IBIAS[0]) is controlled by the BIASINC
register and is used to set the odd denominations in the SET_IBIAS[8:0]. Any direct write to SET_IBIAS[8:1] resets the
LSB.
