Note 1: Master Device is responsible for A / A signal. If a A signal occurs, the MCP45XX/46XX will
abort this transfer and release the bus.
2: The Master Device will Not Acknowledge, and the MCP45XX/46XX will release the bus so the
Master Device can generate a Stop or Repeated Start condition.
3: The MCP45xx/46xx retains the last “Device Memory Address” that it has received. This is the
MCP45XX/46XX 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.
