When interfacing the ADAU144x to other devices in the system, it may be necessary to set the drive strength of each pin.
DRIVE STRENGTH MODES AND SETTINGS
Bit Clock Pad Strength Register (Address 0xE247)
This register controls the pad drive strength of all bit clock pins configured in master mode. The default 2 mA setting should be adequate
for most applications. The 6 mA setting should be used only when the integrity of the signal is compromised.
