Hi,
The 'GPIO57_I2S-MCLK_VIO3_SW' signal is connected to the I2S-MCLK pin of the CYUSB3014 device in the CYUSB3KIT-003 Superspeed Explorer kit. The signal is routed to the rectangular expansion header.
Please tell me the function of this signal.
Regards,
Prachi
This GPIO can be used as an I2S_MCLK if you connect a I2S receiver device to the SuperSpeed Explorer Kit. If you are not using the I2S interface, you can use it as a normal GPIO too.
