@@ -8,9 +8,10 @@ lib_xua Change Log
* ADDED: Application note AN00247: Using lib_xua with lib_spdif (transmit)
* CHANGE: I2S hardware resources no longer used globally and must be passed
to XUA_AudioHub()
* CHANGE: NO_USB define renamed to XUA_USB_EN
* CHANGE: XUA_AudioHub() no longer pars S/PDIF transmitter task
* CHANGE: Moved to lib_spdif (from module_spdif_tx & module_spdif_rx)
* CHANGE: Define NUM_PDM_MICS renamed to XUA_NUM_PDM_MICS
* CHANGE: Define NO_USB renamed to XUA_USB_EN
