Code Question

Please ask your question

reference to datasheet:

The AT24C01C is internally organized as 16 pages of 8 bytes each. The AT24C02C is internally
organized as 32 pages of 8 bytes each.

why make AT24Cxx_type = memorysize - 1, rather than memorysize? which make it cannot access to the last word of eeprom.

    AT24C01  = 127,          /**< AT24C01 type */
