Previously addressed with General Call. Data has been received, NOT ACK has been
returned. Received data will not be saved. Not addressed Slave mode is entered.
A STOP condition or Repeated START has been received, while still addressed as a
Slave. Data will not be saved. Not addressed Slave mode is entered.
Own Slave Address + Read has been received, ACK has been returned. Data will be
transmitted, ACK bit will be received.
Arbitration lost in Slave Address and R/W bit as bus Master. Own Slave Address + Read
has been received, ACK has been returned. Data will be transmitted, ACK bit will be
received. STA is set to restart Master mode after the bus is free again.
Data has been transmitted, ACK has been received. Data will be transmitted, ACK bit will
be received.
