Single UART with I

C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
A slave receiver must generate an acknowledge after the reception of each byte, and a
master must generate one after the reception of each byte clocked out of the slave
transmitter.
There are two exceptions to the ‘a(chǎn)cknowledge after every byte’ rule. The first occurs when
a master is a receiver: it must signal an end of data to the transmitter by
not
signalling an
acknowledge on the last byte that has been clocked out of the slave. The acknowledge
related clock, generated by the master should still take place, but the SDA line will not be
pulled down. In order to indicate that this is an active and intentional lack of
acknowledgement, we shall term this special condition as a ‘negative acknowledge’.
The second exception is that a slave will send a negative acknowledge when it can no
longer accept additional data bytes. This occurs after an attempted transfer that cannot be
accepted.
10.2 Addressing and transfer formats
Each device on the bus has its own unique address. Before any data is transmitted on the
bus, the master transmits on the bus the address of the slave to be accessed for this
transaction. A well-behaved slave with a matching address, if it exists on the network,
should of course acknowledge the master's addressing. The addressing is done by the
first byte transmitted by the master after the START condition.
