# Favr-32 customization

if BOARD_FAVR_32

config BOARD_FAVR32_ABDAC_RATE
int "DAC target rate"
default 44100
range 32000 50000
help
Specify the target rate the internal DAC should try to match. This
will use PLL1 to generate a frequency as close as possible to this
rate.

Must be within the range 32000 to 50000, which should be suitable to
generate most other frequencies in power of 2 steps.

Ex:
48000 will also suit 24000 and 12000
44100 will also suit 22050 and 11025
32000 will also suit 16000 and 8000
