While pin P1s_00 and pin P1s_01 are assigned GPIO role, CD/WP signal of internal IP (SDIO) can be set by
using IOFIX_APP. Figure I/O Configuration-14 shows connecting diagram of CD/WP signal to SDIO IP.

I2S0
When you use a pin as I2S role, you need to select I2S role by using IOCAPP_IOMD, as well as decide in which
mode I2S role should be played, master or slave. According to the decision, you need to set IOOEN_APP
adequately.
The following are settings that pin P1v_{00,01,02,03} are used as the I2S master.
