R = Read/Write select bit.
CRC-8 error check byte is added in the data string dur-
ing each read and/or write sequence. Enable PEC by
writing a ‘1’ to r8Bh[7].
The CRC-8 byte is calculated using the polynomial
The PEC calculation includes all bytes in the transmis-
sion, including address, command, and data. The PEC
calculation does not include ACK, NACK, START, STOP,
or REPEATED START.
The MAX16065/MAX16066 use eight command codes
for block read, block write, and other commands. See
Table 28 for a list of command codes.
To initiate a software reboot, send A7h using the send byte
format. A software-initiated reboot is functionally the same

as a hardware-initiated power-on reset. During boot-up,
flash configuration data in the range of 230h to 28Ch is
copied to r30h to r8Ch registers in the default page.
Send command code A8h to trigger a fault store to flash.
Configure the Critical Fault Log Control register (r6Dh) 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 to 28Dh).
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 to 08Dh). Send command code ABh to access the
user flash-page (addresses from 300h to 39Fh and 3B0h
to 3FFh), and send command code ACh to return to the
flash page.
ACTION
SMBus Slave Address Register. Set to 00h to use A0
pin address setting.
