6-Channel, Flash-Configurable System Manager
with Nonvolatile Fault Registers
Slave Address
Use the slave address input, A0, to allow multiple identi-
cal devices to share the same serial bus. Connect A0 to
GND, DBP (or an external supply voltage greater than
2V), SCL, or SDA to set the device address on the bus.
See Table 26 for a listing of all possible 7-bit addresses.
The slave address can also be set to a custom value by
loading the address into register r8Bh[6:0]. See Table
25. If r8Bh[6:0] is loaded with 00h, the address is set by
input A0. Do not set the address to 09h or 7Fh to avoid
address conflicts. The slave address setting takes effect
immediately after writing to the register.
Packet Error Checking (PEC)
The MAX16067 features a packet-error checking (PEC)
mode that is useful to improve the reliability of the com-
munication bus by detecting bit errors. By enabling PEC,
an extra CRC-8 error check byte is added in the data
string during each read and/or write sequence. Enable
PEC by writing a ‘1’ to r8Bh[7].
The CRC-8 byte is calculated using the polynomial
C = X 8 + X 2 + X + 1
The PEC calculation includes all bytes in the transmis-
sion, including address, command, and data. The PEC
Table 25. SMBus Settings Register
calculation does not include ACK, NACK, START, STOP,
or REPEATED START.
Command Codes
The MAX16067 uses eight command codes for block
read, block write, and other commands. See Table 27
for a list of command codes.
To initiate a software reboot, send A7h using the send
byte format. A software-initiated reboot is function-
ally the same as a hardware-initiated power-on reset.
During boot-up, flash configuration data in the range
of 230h–28Ch is copied to r30h–r8Ch registers in the
default page.
Send command code A8h to trigger a fault store to flash.
Configure the Critical Fault Log Control register (6Dh) to
store ADC conversion results and/or fault flags.
While in the flash page, send command code A9h to
access the flash page (addresses from 200h–2FFh).
Once command code A9h has been sent, all addresses
are recognized as flash addresses only. Send command
code AAh to return to the default page (addresses from
000h–0FFh). Send command code ABh to access the
user flash-page (addresses from 300h–3FFh), and send
command code ACh to return to the flash page.
