Description: 如果RTL8019AS使用了93C46,那么如何通过单片机对它进行编程呢?
93C46是一个有128字节的eeprom,可以是8位或16位的存储模式,在RTL8019AS中,用的是16位的模式,也就是总共有64个16位的存储单元.16位方式下,存储地址为0---63 .每个地址存储两个字节,低位字节在前,高位字节在后(这跟单片机的存储相反,单片机是高位在前,低位在后).
下表是93c46存储的内容,地址是用字节表示的.-used 93C46, SCM then how to program it? 93C46 is a 128 bytes of eeprom. can be 8 or 16 bit memory model, RTL8019AS, with the 16 model, is a total of 64 of 16 storage units .16-mode, Storage at 0--- 63. two each address byte memory, the low byte first, After the high byte (SCM storage with the contrary, the former SCM is high, lows in the latter). The following table is 93 c46 store the contents of the addresses are used byte said. Platform: |
