Product Specification
Image Information 1 Registers (VC0 to VC15)
The Image Information 1 registers are described in
and provide image
information for line count and byte count per VC. The byte count gets updated whenever a
long packet (from Data Types 0x18 and above) for the corresponding virtual channel is
processed by the control FSM. The line count is updated whenever the packet is written into
the line buffer.
Image Information 2 Registers (VC0 to VC15)
The Image Information 2 registers are described in
and provide the image
information Data Type. The Data Type is updated whenever a long packet (Data Types 0x18
and above) for the corresponding virtual channel is processed by the control FSM.
AXI IIC Registers
The AXI IIC registers are available when
