I2C Command is "A6,A5,A4,A3,A2,A1,A0,R/W
所以發出去的 Slave Address 為 0x02時，SSPADD (Slave Address) 也必須一樣為 0x02。需注意一下，SSPADD 的 b0 是沒有用的，設定的位址就跟 Command 一樣就好了。

請問我拿兩顆PIC18F4550 一顆當master , 一顆當slaver
當master用I2C傳Address(ex. 0x02) 給slaver 時(SSPADD設0x01), slaver並沒有發生中斷 ??? 但master用General call (0x00) 時 , slaver就會產生中斷 , 這是什麼問題呢??? 我的SSPADD有設對阿 , 還是還要設定其它的東西?
