Channel States
A NC channel can be in one of the following states:
For normal operation mode, the MC should always send the Clear Initial State
command as the first command to the channel.
Discovery
After interface power-up, the MC should perform a discovery process to discover the
NCs that are connected to it.
This process should include an algorithm similar to the following:
Configurations
This section details different configurations that should be performed by the MC.
It is considered a good practice that the MC does not consider any configuration valid
unless the MC has explicitly configured it after every reset (entry into the initial state).
As a result, it is recommended that the MC re-configure everything at power-up and
channel/package resets.
1. Initial State - In this state, the channel only accepts the Clear Initial State
2. Active state - This is the normal operational mode. All commands are accepted.
1. For package_id=0x0 to MAX_PACKAGE_ID
command (the package also accepts the Select Package and De-Select Package
commands).
a. Issue Select Package command to package ID package_id
b. If a response was received then
c.
For internal_channel_id = 0x0 to MAX_INTERNAL_CHANNEL_ID
Issue a Clear Initial State command for package_id | internal_channel_id (the
combination of package_id and internal_channel_id to create the channel ID).
If a response was received then
Consider internal_channel_id as a valid channel for the package_id package
The MC can now optionally discover channel capabilities and version ID for the
channel
Else (If not a response was not received, then issue a Clear Initial State
command three times.
Issue a De-Select Package command to the package (and continue to the next
package).
Else, if a response was not received, issue a Select Packet command three times.
