|

|
.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 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.
