About Result Codes
There are two types of
Result Code
values the device can return in its response:
Generic
result codes
(listed in
), which have the same meaning for all commands, and
command-specific
result
codes, which can have different meanings for different commands, and are listed with every command in
this section. Generic result codes always have the most significant bit set to zero, and command-specific
result codes always have the most significant bit set to one.
