Each AXI input interface has its own reset signal.
The reset signals,
s_axi_cpu_aresetn
, s_axis_video_aresetn
and
s_axis_audio_aresetn
are for S_AXI_CPU_IN
,
VIDEO_OUT
(AXI4-Stream Video Interface), and
AUDIO_OUT
respectively.
These three reset signals are active-Low. Because
the reset signal is used across multiple sub-blocks in the subsystem, keep the
system in the reset state until all the clocks are stabilized. You can use the
locked
signal from the clock generation block as a reset
signal.
Note: There is
no dedicated hardware reset for VIDEO_OUT interface when Native Video interface is
selected. However, the HDMI 2.1 RX Subsystem outputs a
video_rst
signal, which you can use to reset its supporting Native Video
Source processing modules.
