byte goes into the internal register of the MAX8831
selected by the command byte. If multiple data bytes
are transmitted before a STOP condition is detected,
these bytes are stored in subsequent MAX8831 internal
registers because the command byte address auto-
increments (Figure 11).
Message Format for Reading
The MAX8831 is read using the MAX8831’s internally
stored command byte as an address pointer, the same
way the stored command byte is used as an address
pointer for a write. The pointer autoincrements after
each data byte is read, using the same rules as for a
write. Thus, a read is initiated by first configuring the
MAX8831’s command byte by writing the command
byte corresponding to the beginning register address
to be read. The master can now read n consecutive
bytes from the MAX8831, by first writing the read com-
mand (0x9B) to the MAX8831 (Figures 12 and 13).
When performing read-after-write verification, reset the
command byte ’s address since the stored byte
address is autoincremented after the write.
MAX8831 I 2 C Registers
The MAX8831 contains 19 registers that are accessible
through the I 2 C interface (Table 3). See the register
descriptions for more details. The register contents are
reset to the default RESET values (shown in Table 3) if
V DD goes low.
ON/OFF Control Register
The ON/OFF control register (ON/OFF_CNTL) enables
and disables the LED1–LED5 current regulators (Table
4). Write a 1 to the LED#_EN bit to enable that
