/*
 * ReadEErow prototype:
 * Parameters Definition:
 * Page:        is the 8 most significant bits of the source address in EEPROM
 * Offset:      is 16 least significant bits of the source address in EEPROM
 * DataOut:     is the 16-bit address of the destination RAM location or array
 * Size:        is the number of words to read from EEPROM and is a value of 1 or 16
 * Return Value:
 * Function returns ERROREE (or -1) if Size is invalid

Em dùng thử mà kết quả ko chính xác, đồng thời ko hiểu rõ ý nghĩa của Page , Offset lắm
Nhờ mọi người giúp đỡ !
