Video FIFO 2 underflow/overflow
: this bit is set when the video FIFO 2
has an overflow/underflow. This bit is reset when reloading the DMA
base address or by writing a logic 1 to the VFOU bit in the ISR.
Video FIFO 1 overflow
: this bit is set when the video FIFO 1 has an
overflow. This bit is reset when reloading the DMA base address or by
writing a logic 1 to the VFOU bit in the ISR.
Audio input FIFO 2 underflow
: this bit is set when the audio input
FIFO 2 has an underflow. This bit is reset by restarting the DMA channel
or by writing a logic 1 to the AFOU bit in the ISR.
Audio output FIFO 2 overflow
: this bit is set when the audio output
FIFO 2 has an overflow. This bit is reset by restarting the DMA channel
or by writing a logic 1 to the AFOU bit in the ISR.
Audio input FIFO 1 underflow
: this bit is set when the audio input
FIFO 1 has an underflow. This bit is reset by restarting the DMA channel
or by writing a logic 1 to the AFOU bit in the ISR.
Audio output FIFO 1 overflow
: this bit is set when the audio output
FIFO 1 has an overflow. This bit is reset by restarting the DMA channel
or by writing a logic 1 to the AFOU bit in the ISR.
reserved
Vertical Gate
: this bit reflects the vertical gate at the HPS output
Line Qualifier Gate
: this bit reflects the horizontal gate at the HPS
output
Event Counter 5 Status
: this bit is set when the event counter 5
exceeds its threshold. This bit is reset by writing a logic 1 to the ECS bit
in the ISR.
Event Counter 4 Status
: this bit is set when event counter 4 exceeds
its threshold. This bit is reset by writing a logic 1 to the ECS bit in the
ISR.
Event Counter 2 Status
: this bit is set when event counter 2 exceeds
its threshold. This bit is reset by writing a logic 1 to the ECS bit in the
ISR.
Event Counter 1 Status
: this bit is set when event counter 1 exceeds
its threshold. This bit is reset by writing a logic 1 to the ECS bit in the
ISR.
