+.Sh NAME
+.Nm tea5767
+.Nd Philips/NXP TEA5767 FM Chip
+.Sh SYNOPSIS
+.Cd "tea5767radio* at iic? addr 0x60 flags 0x00"
+.Cd "radio* at tea5767radio?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the Philips/NXP TEA5767 FM stereo radio.
+.Pp
+The
+.Nm
+can tune in the range 87.5 \- 108.0 MHz, perform hardware signal search
+and supports mono/stereo toggling.
+.Pp
+The flags control the FM Band, XTAL and PLL values as follows:
+.Bl -tag -width Ds
+.It 0x01
+sets the FM Band to Japan.
+.It 0x02
+sets the PLL bit.
+.It 0x04
+sets the XTAL bit.
+.It 0x08
+force enables hardware search support.
+.Sh SEE ALSO
+.Xr iic 4 ,
+.Xr radio 4 ,
+.Xr radio 9 ,
+.Rs
+.%A TEA5767
+.%T Low-power FM stereo radio
+.%N Rev. 05
+.%D 26 January 2007
+.Re
+.Sh 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
+.Nm
+driver tries to detect the crystal quality during attachment. If the crystal
+of insufficient accuracy was detected, hardware search function is disabled.
+It can be forcefully re-enabled by setting the 0x08 flag.
