8) The slave asserts an ACK on SDA.
9) The slave sends the 8-bit byte count (16).
10) The master asserts an ACK on SDA.
11) The slave sends 8 bits of data.
12) The master asserts an ACK on SDA.
13) Repeat steps 11 and 12 up to fifteen times.
14) The master asserts a NACK on SDA.
15) The master sends a STOP condition.
