//函数：long g20(uchar c1, uchar c2, uchar c3, uchar c4)
//功能：计算汉字点阵在芯片中的地址
//参数：c1,c2,c3,c4：4字节汉字内码通过参数c1,c2,c3,c4传入，双字节内码通过参数c1,c2传入，c3=0,c4=0
//返回：汉字点阵的字节地址(byte address)。如果用户是按 word mode 读取点阵数据，则其地址(word
//address)为字节地址除以2，即：word address = byte address / 2 .
//例如：“啊”字的内码为0xb0a1,则byte address = g(0xb0,0xa1,0x00,0x00) *32+0xa7700
//word address = byte address / 2
//“ ”字的内码为0x8139ee39,则byte address = g(0x81,0x39,0xee,0x39) *32+0xa7700
//word address = byte address / 2
//说明：在以上计算字节地址中byte address = g(0xb0,0xa1,0x00,0x00) *32+0xa7700的0xa7700是15X16
//点阵字库相对整个字库芯片0000 0000的偏移地址
