Figures 14a and 14b. Writing to the IC
1) The master sends a START command.
2) The master sends the 7-bit slave address followed
by a write bit.
3) The addressed slave asserts an acknowledge by
pulling SDA low.
4) The master sends an 8-bit register pointer.
5) The slave acknowledges the register pointer.
6) The master sends a REPEATED START condition.
7) The master sends the 7-bit slave address followed
by a read bit.
8) The slave asserts an acknowledge by pulling SDA low.
9) The slave sends the 8-bit data (contents of the
register).
10) The master asserts a not acknowledge by keeping
SDA high.
11) The master sends a STOP condition.
In addition, the IC can read a block of multiple sequential
registers as shown in Figure 15b. Use the following pro-
cedure to read a sequential block of registers:
1) The master sends a START command.
2) The master sends the 7-bit slave address followed
by a write bit.

3) The addressed slave asserts an acknowledge by
pulling SDA low.
4) The master sends an 8-bit register pointer of the
first register in the block.
5) The slave acknowledges the register pointer.
6) The master sends a REPEATED START condition.
7) The master sends the 7-bit slave address followed
by a read bit.
8) The slave asserts an acknowledge by pulling SDA low.
9) The slave sends the 8-bit data (contents of the reg-
ister).
10) The master asserts an acknowledge by pulling SDA
low when there is more data to read, or a not
acknowledge by keeping SDA high when all data
has been read.
11) Steps 9 and 10 are repeated for as many registers
in the block, with the register pointer automatically
incremented each time.
12) The master sends a STOP condition.
