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.
