17.12 SET_ACTIVE COMMAND
The SET_ACTIVE command consists of a command byte
(0x8B) and a data byte from the host. This command sets the
time that the LM8322 stays active without detecting a key-
press or key-release event before entering Halt mode. The
default active time is 500 milliseconds. The host can program
ACTIVETIME from 4–1020 milliseconds with a granularity of
4 milliseconds.

17.13 READ_ERROR COMMAND
The READ_ERROR command consists of a command byte
(0x8C) from the host and a data byte from the LM8322. After
reading an interrupt code that indicates an error condition, this
command is used to read an error code that indicates the
cause of the error condition.
