After the Start condition, each bit of data in
transmission needs to be settled for a time specified by
t
Sensor Serial Interface Timing Specifications section).
4.1.6
Each receiving device, when addressed, is obliged to
generate an ACK bit after the reception of each byte.
The master device must generate an extra clock pulse
for ACK to be recognized.
The acknowledging device pulls down the SDA line for
t
the master. SDA also needs to remain pulled down for
t
During read, the master must signal an End-of-Data
(EOD) to the slave by not generating an ACK bit (NAK)
once the last bit has been clocked out of the slave. In
this case, the slave will leave the data line released to
enable the master to generate the Stop condition.
