Using I2S-pins as GPIO's with 32bit GPIF?

Hi,

if I set the FX3 to use 32bit GPIF: can I use the I2S-pins [GPIO50...52, 57] as simple or complex GPIO's?

The FX3's pin-decription doesn't show this clearly:

 

        GPIO+SPI GPIO+UART GPIO only GPIF II - 32
(FX3)+UART+I2S
GPIO+I2S UART+SPI+I2S
D1 VIO3 I/O GPIO[50] GPIO GPIO GPIO I2S_CLK GPIO I2S_CLK
D2 VIO3 I/O GPIO[51] GPIO GPIO GPIO I2S_SD GPIO I2S_SD
D3 VIO3 I/O GPIO[52] GPIO GPIO GPIO I2S_WS GPIO I2S_WS
C1 VIO4 I/O GPIO[54] SPI_SSN UART_CTS GPIO UART_CTS I2S_CLK SPI_SSN
C2 VIO4 I/O GPIO[55] SPI_MISO UART_TX GPIO UART_TX I2S_SD SPI_MISO
D5 VIO4 I/O GPIO[56] SPI_MOSI UART_RX GPIO UART_RX I2S_WS SPI_MOSI
C4 VIO4 I/O GPIO[57] GPIO GPIO GPIO I2S_MCLK I2S_MCLK I2S_MCLK

Regards!

Yes. You can.
