STOP bit Control Byte 1 010 S 1 A1 A0 1 A Fixed Address Variable Address Read bits P 0 000 0 0 0 D8 A1 Read bit D3 D7 D6 D5 D4 D2 D1 D0 A2 Read Data bits Note 1: Master Device is responsible for A / A signal. If a A signal occurs, the MCP44XX will abort this transfer and release the bus. 2: The Master Device will Not Acknowledge, and the MCP44XX will release the bus so the Master Device can generate a Stop or Repeated Start condition. 3: The MCP44XX retains the last “Device Memory Address” that it has received. This is the MCP44XX does not “corrupt” the “Device Memory Address” after Repeated Start or Stop conditions. 4: The Device Memory Address pointer defaults to 00h on POR and BOR conditions.
