# 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.
