Figure 19. Writing to the MAX8834Y/MAX8834Z
5) The slave acknowledges the register pointer.
6) The master sends a REPEATED START (Sr) 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.
11) The master sends a STOP (P) condition.
In addition, the MAX8834Y/MAX8834Z can read a block
of multiple sequential registers as shown in section B of
Figure 20. Use the following procedure 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.
22
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.
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.
