ADAU1381
Register 16430 (0x402E), Serial Port Pad Control 1
Bit 3, ADC_SDATA Pin Drive Strength
This bit sets the drive strength of the ADC_SDATA pin. Low mode
yields 2 mA when IOVDD = 3.3 V, or 0.75 mA when IOVDD =
1.8 V. High mode yields 4 mA when IOVDD = 3.3 V, or 1.5 mA
when IOVDD = 1.8 V.
Bit 2, DAC_SDATA Pin Drive Strength
This bit sets the drive strength of the DAC_SDATA pin. Low mode
yields 2 mA when IOVDD = 3.3 V, or 0.75 mA when IOVDD =
1.8 V. High mode yields 4 mA when IOVDD = 3.3 V, or 1.5 mA
when IOVDD = 1.8 V.

Bit 1, LRCLK Pin Drive Strength
This bit sets the drive strength of the LRCLK pin. Low mode yields
2 mA when IOVDD = 3.3 V, or 0.75 mA when IOVDD = 1.8 V.
High mode yields 4 mA when IOVDD = 3.3 V, or 1.5 mA when
IOVDD = 1.8 V.
Bit 0, BCLK Pin Drive Strength
This bit sets the drive strength of the BCLK pin. Low mode yields
2 mA when IOVDD = 3.3 V, or 0.75 mA when IOVDD = 1.8 V.
High mode yields 4 mA when IOVDD = 3.3 V, or 1.5 mA when
IOVDD = 1.8 V.
