E.g. If you want to write 4 Bytes data to the AMIC A25LQ64, The packet form Host should be “1 Byte Command + 3 Bytes Address + 4 Bytes Data”. When single packet processing is completed, the E2S will be returned 8 Bytes data to Host. www.forenex.com.tw - 25 -... - Page 26 The packet form Host should be “1 Byte Command + 3 Bytes Address + 4 Bytes Dummy” When single packet processing is completed, the E2S will be returned 8 Bytes data to Host.
