1. Typical values: T_A = 25°C and 3.0 V.
2. All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are
100 percent tested.
3. V_CCA and V_CCD connected together.
4. SS = V_CCA = V_CCD, XCLK = MOSI = V_SSA= V_SSD and all other pins floating.
5. Measured with AutoMute feature disabled.
