Note to
(1) These ports are present only if Alpha blending is on in the parameter editor. Note that alpha channel ports are created for layer zero even though
no alpha mixing is possible for layer zero (the background layer). These ports are ignored and can safely be left unconnected or tied to 0.

alpha_in_N port Avalon-ST endofpacket signal. This signal marks the
end of an Avalon-ST packet.
alpha_in_N port Avalon-ST alpha ready signal. This signal indicates
when the MegaCore function is ready to receive data.
alpha_in_N port Avalon-ST startofpacket signal. This signal marks
the start of an Avalon-ST packet.
alpha_in_N port Avalon-ST alpha valid signal. This signal identifies
the cycles when the port should input data.
control slave port Avalon-MM address bus. Specifies a word offset
into the slave address space.
control slave port Avalon-MM chipselect signal. The control port
ignores all other signals unless this signal is asserted.
control slave port Avalon-MM readdata bus. These output lines are
used for read transfers.
control slave port Avalon-MM write signal. When this signal is
asserted, the control port accepts new data from the writedata bus.
control slave port Avalon-MM writedata bus. These input lines are
used for write transfers.
din_N port Avalon-ST data bus for port din for layer N. Pixel data is
transferred into the MegaCore function over this bus.
din_N port Avalon-ST endofpacket signal. This signal marks the end of
an Avalon-ST packet.
din_N port Avalon-ST ready signal. This signal indicates when the
MegaCore function is ready to receive data.
din_N port Avalon-ST startofpacket signal. This signal marks the
start of an Avalon-ST packet.
din_N port Avalon-ST valid signal. This signal identifies the cycles
when the port should input data.
dout port Avalon-ST data bus. Pixel data is transferred out of the
MegaCore function over this bus.
dout port Avalon-ST endofpacket signal. This signal marks the end of
an Avalon-ST packet.
dout port Avalon-ST ready signal. This signal is asserted by the
downstream device when it is able to receive data.
dout port Avalon-ST startofpacket signal. This signal marks the start
of an Avalon-ST packet.
dout port Avalon-ST valid signal. This signal is asserted when the
MegaCore function outputs data.
