SDK14 52832 PDM

I hava a board of 52DK,now

I develp a project about pdm using the ic mp34db02

i test the all kinds of sdk ,I find the sdk14.0 ‘s throughput is Complacent,

soI must use sdk14.0

but  I I don't know how to use PDM driver in sdk File directory\components\drivers_nrf\pdm

It's different with the older version
