"Associates a Handler Configuration ID With A Mode" (APP/LPA)

Description:

For each of the 8 available modes, an individual handler can take data using one of its 32 available internal configurations. This command associates one of these 32 configuration IDs with a specific mode. Each of the 8 available handler masks maps to a mode. A set bit in any of these 8 masks will take the handler corresponding to that bit position and create an association between the specified configuration ID and the mode.

Fields:

CFG_ID (index)

Attribute(s):  

Brief:  "LPA Configuration ID"

Instance(s):  cfg

Value that binds a set of event handler configurations to a single unique identifier.

CPU_MSK (index)

Attribute(s):  

Brief:  "CPU Mask"

Instance(s):  cpus

Mask of logical IDs for target CPUs.

DB_ID (index)

Attribute(s):  

Brief:  "LPA_DB Instance ID"

Instance(s):  db

Specifies the numerical ID of an LPA configuration database instance. Each instance is generally associated with a distinct LPA category, such as norma or diagnostics.

EVH_MSK (index)

Attribute(s):  

Brief:  "Event Handler Mask"

Instance(s):  handlers

Mask of event handler IDs as specified in a LPA_DB instance.
