All data must be transmitted per byte, with no limit to the number of bytes transmitted per data
transfer. After each byte, the slave-receiver generates an acknowledge bit (ACK)
When a slave-receiver doesn’t acknowledge the slave address or received data, the master must
abort the transfer. The slave must leave SDA high so that the master can generate the STOP con-
dition
Figure A-4:
If the master is receiving the data (master-receiver), it generates an acknowledge signal for each
received byte of data, except for the last byte. To signal the end of data to the slave-transmitter,
the master does not generate an acknowledge (not acknowledge). The slave then releases the
SDA line so the master can generate the STOP condition. The master can also generate the
STOP condition during the acknowledge pulse for valid termination of data transfer.
If the slave needs to delay the transmission of the next byte, holding the SCL line low will force
the master into a wait state. Data transfer continues when the slave releases the SCL line. This
allows the slave to move the received data or fetch the data it needs to transfer before allowing
the clock to start. This wait state technique can also be implemented at the bit level,
