5:0atestATEST mode allows the user to check for the internal die voltages to make make sure the supply voltages are within the range. When ATEST mode is programmed, the internal die voltages can be measured at the TXENABLE pin. The TXENABLE pin (A32 for DAC3482IRKD and N9 for DAC3482IZAY) must be floating without any pull-up or pull-down resistors. In ATEST mode, the TXENABLE and sif_txenable logics are bypassed, and output will be active at all time.000000
