Set to 1 if acknowledge bit from Slave Device is not 0. Automatically reset
when the new bus transaction is started.
Write a 1 to start I
transaction is done. This bit should be treated as a “busy” indicator on
reading. If it is high, the serial read/write operations are not completed and
no new address or data should be written.
Set to 1 for 2 byte read or write operations. Set to 0 for 1-byte operations.
