CAVEATS
Many popular TEA5767 evaluation boards feature low quality 32.768kHz crystals. The inaccuracy of these crystals may often lead to malfunction of the hardware search funciton. Therefore, the tea5767 driver tries to detect the crystal quality during attachment. If the crystal of insufficient accuracy was detected, the hardware search function is disabled. It can be forcefully re-enabled by setting the 0x08 flag.
