10.1 SMB Communication
The set of read/write operations over the SMBus are not specific to any gas gauge. These are provided as
general-purpose communication tools (

Hexadecimal value and Decimal value convert between hexadecimal and decimal as soon as values are
typed into the boxes. Invalid values may cause erroneous results.
When scaling converted hexadecimal values to a higher number of bytes, follow these rules:
•
When unsigned is selected, the left pad contains zeroes.
• When signed is selected, the left pad contains zeroes for a positive number, or the left pad contains F
for negative numbers.
