R
Video FIFO 2 underow/overow: this bit is set when the video FIFO 2
has an overow/underow. This bit is reset when reloading the DMA
base address or by writing a logic 1 to the VFOU bit in the ISR.
VF1
11
R
Video FIFO 1 overow: this bit is set when the video FIFO 1 has an
overow. This bit is reset when reloading the DMA base address or by
writing a logic 1 to the VFOU bit in the ISR.
AF2_in
10
R
Audio input FIFO 2 underow: this bit is set when the audio input
FIFO 2 has an underow. This bit is reset by restarting the DMA channel
or by writing a logic 1 to the AFOU bit in the ISR.
AF2_out
9
R
Audio output FIFO 2 overow: this bit is set when the audio output
FIFO 2 has an overow. This bit is reset by restarting the DMA channel
or by writing a logic 1 to the AFOU bit in the ISR.
AF1_in
8
R
Audio input FIFO 1 underow: this bit is set when the audio input
FIFO 1 has an underow. This bit is reset by restarting the DMA channel
or by writing a logic 1 to the AFOU bit in the ISR.
AF1_out
7
R
Audio output FIFO 1 overow: this bit is set when the audio output
FIFO 1 has an overow. This bit is reset by restarting the DMA channel
or by writing a logic 1 to the AFOU bit in the ISR.

R
Vertical Gate: this bit reects the vertical gate at the HPS output
LNQG
4
R
Line Qualier Gate: this bit reects the horizontal gate at the HPS
output
EC5S
3
R
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.
EC4S
2
R
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.
EC2S
1
R
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.
EC1S
0
R
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.
