How do you set operating mode of PN532 NFC reader/writer?

Tutorial on ITEAD PN532 states which codes should be used to set system into I2C (SET0=1 SET1=0) and SPI (SET0=0 SET1=1) mode (default is UART with two 0s), but I am a noob and cannot find how to actually set them.


Set0 and Set1 are switches on the ITEAD PN532 card - physical switches indicated on the card itself with the words "SET0" and "SET1". To enable SPI mode, make sure SET0 is set to L (Low) and SET1 is set to H (High) by sliding the white switch to the correct position (marked with L and H respectively).
