Send Byte
The send byte protocol allows the master device to
send one byte of data to the slave device (see Figure
9). The send byte presets a register pointer address for
a subsequent read or write. The slave sends a NACK
instead of an ACK if the master tries to send a memory
address or command code that is not allowed. If the
master sends A5h or A6h, the data is ACK, because this
could be the start of the write block or read block. If the
master sends a STOP condition before the slave asserts

The master sends the 7-bit slave address and a

The addressed slave asserts an ACK on SDA.

an ACK, the internal address pointer does not change.
If the master sends A7h, this signifies a software reboot.
The send byte procedure is as follows:
To write a single byte, only the 8-bit memory address
and a single 8-bit data byte are sent. The data byte is
written to the addressed location if the memory address

The addressed slave asserts an ACK on the data
line.
The master sends an 8-bit memory address.
Receive Byte
The receive byte protocol allows the master device to
read the register content of the MAX16068 (see Figure
9). The flash or register address must be preset with a
send byte or write word protocol first. Once the read
is complete, the internal pointer increases by one.

6) The master generates a STOP condition.
Write Byte
The write byte protocol (see Figure 9) allows the mas-
ter device to write a single byte in the default page,
extended page, or flash page depending on which page is
currently selected. The read byte procedure is as follows:
1) The master sends a START condition.
