BIT 7 - VT Size Error Interrupt Status:
This RESET-upon-READ bit-field indicates whether or not the "VT-De-Mapper" block has generated the "VT Size Error"
Interrupt since the last read of this register. The VT-De-Mapper block will generate the "VT Size Error" Interrupt anytime
it declares the "VT Size Error" defect condition.
0 - Indicates that the VT Size Error Interrupt has NOT occurred since the last read of this register.
1 - Indicates that the VT Size Error Interrupt has occurred since the last read of this register.
BIT 6 - Change of LOP-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
LOP-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 the VT-De-Mapper block declares the LOP-V defect condition.
Whenever the VT-De-Mapper block clears the LOP-V defect condition.
0 - Indicates that the "Change of LOP-V Defect Condition" Interrupt has NOT occurred since the last read of this
register.
1 - Indicates that the "Change of LOP-V Defect Condition" Interrupt has occurred since the last read of this register.
BIT 5 - Change of RFI-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
RFI-V Defect Condition" Interrupt since the last read of this register. The VT-De-Mapper block will generate this interrupt
