Available scenarios:
|
1: Single Port 0 used by THC0
|
- THC0 Enabled
|
- Port0 assigned to THC0
|
- Port1 unassigned
|
- THC1 will be automatically Disabled.
|
2: Both ports used by THC0
|
- THC0 Enabled
|
- Port0 assigned to THC0
|
- Port1 assigned to THC0
|
- THC1 will be automatically Disabled.
|
3: Port 0 used by THC0 and Port 1 used by THC1
|
- THC0 Enabled
|
- Port0 assigned to THC0
|
- THC1 Enabled
|
- Port1 assigned to THC1.
|
<b>4: Both Ports unassigned.</b>
|
Both THC Controllers will be disabled in that case.

@note
|
Invalid scenario that will cause ASSERT.
|
1. Same port Number assigned to THC0 or THC1.
|
2. Two Ports assigned to THC1.
