Cxmc3349 is a Chinese character library chip with 16x16 lattice, which supports GB2312 simplified Chinese characters (including national beaconAuthorized), ASCII characters

The user can use this manual to provide
The address of the character lattice in the chip can be calculated by the method, and the information of the character lattice can be read out continuously from the address.
In addition to the above font, cxmc3349 also provides 16 sectors, 4K bytes or 16 pages for each sector, 256 bytes for each page,
The free write space address range is 6ffff-7ffff. It only supports upper computer burning and can be rewritten more than 100000 times
