BIT 5 - Change of VT Path Trace Message Unstable Defect Condition Interrupt Status:
This RESET-upon-READ bit-field indicates whether or not the "Change of VT Path Trace Message Unstable Defect
Condition" Interrupt has occurred since the last read of this register. The VT-De-Mapper block will generate this interrupt
in response to either of the following conditions.
Whenever the VT-De-Mapper block declares the "VT Path Trace Message Unstable" Defect condition.
Whenever the VT De-Mapper block clears the "VT Path Trace Message Unstable" Defect condition.
0 - Indicates that the "Change of VT Path Trace Message Unstable Defect Condition" Interrupt has NOT occurred
since the last read of this register.
1 - Indicates that the "Change of VT Path Trace Message Unstable Defect Condition" Interrupt has occurred since
the last read of this register.
BIT 4 - New VT Path Trace Message Interrupt Status:
This RESET-upon-READ bit-field indicates whether or not the "New VT Path Trace Message" Interrupt has occurred
since the last read of this register. The VT-De-Mapper block will generate this interrupt whenever it has "accepted" a
new "VT Path Trace Message" via the incoming VT-data-stream.
0 - Indicates that the "New VT Path Trace Message" Interrupt has NOT occurred since the last read of this register.
1 - Indicates that the "New VT Path Trace Message" Interrupt has occurred since the last read of this register.
BIT 3 - Change of TIM-V Defect Condition Interrupt Status:
This RESET-upon-READ bit-field indicates whether or not the "VT-De-Mapper" block has generated the "Change of
TIM-V Defect Condition" interrupt since the last read of this register. The VT-De-Mapper block will generate this
interrupt in response to either of the following conditions.
Whenever it declares the TIM-V Defect condition.
Whenever it clears the TIM-V Defect condition.
0 - Indicates that the "Change of TIM-V Defect Condition" interrupt has NOT occurred since the last read of this
register.
1 - Indicates that the "Change of TIM-V Defect Condition" interrupt has occurred since the last read of this register.
