Table 04h (Table 01h in DS1859 Configuration), 8Ch: Main Device Address
FACTORY DEFAULT:
MEMORY TYPE:
Contains the Main Device address. If ADFIX = 1, then the value in this register determines the I
Device memory. If ADFIX = 0, the slave address is A2h. There are 128 possible addresses that can be programmed. If ADFIX = 1
and this register was changed to A0h, GBIC memory will not be addressed.
