Fig. 6: Read Mode Sequence
This is followed by another START condition from
the master and the device address repeated with
the RW bit set to 1. The STA002 acknowledges
this and outputs the byte addressed by the inter-
nal byte address counter.
The master does not acknowledge the received
byte, but terminates the transfer with a STOP
condition.

1.4.3 Sequential address read
This mode can be initiated with either a current
address read or a random address read. How-
ever in this case the master does acknowledge
the data byte output and the STA002 continues to
output the next byte in sequence.
To terminate the stream of bytes the master does
not acknowledge the last received byte, but termi-
nates the transfer with a STOP condition.
The output data stream is from consecutive byte
addresses, with the internal byte address counter
automatically incremented after each byte output.
