control_readdata Out
control slave port Avalon-MM readdata bus. These
output lines are used for read transfers.
(4)
control_readdatavalid Out
control slave port Avalon-MM readdatavalid bus. The
MegaCore function asserts this signal when the
readdata
bus contains valid data in response to the
read signal.
(4)
control_waitrequest Out control slave port Avalon-MM waitrequest signal.
(4)
control_byteenable In
control slave port Avalon-MM byteenable bus. This bus
enables specific byte lane or lanes during transfers. Each
bit in
byteenable corresponds to a byte in writedata
and
readdata . During writes, byteenable specifies
which bytes are being written to; the slave ignores other
bytes. During reads,
byteenable indicates which bytes
the master is reading. Slaves that simply return
readdata
with no side effects are free to ignore
byteenable during
reads.
(4)
edi_read_master_address Out
edi_read_master port Avalon-MM address bus. This
bus specifies a byte address in the Avalon-MM address
space.
(1)
edi_read_master_read Out
edi_read_master port Avalon-MM read signal. The
MegaCore function asserts this signal to indicate read
requests from the master to the system interconnect
fabric.
(1)
edi_read_master_burstcount Out
edi_read_master port Avalon-MM burstcount signal.
This signal specifies the number of transfers in each
burst.
(1)
edi_read_master_readdata In
edi_read_master port Avalon-MM readdata bus. These
input lines carry data for read transfers.
(1)
edi_read_master_readdatavalid In
edi_read_master port Avalon-MM readdatavalid
signal. The system interconnect fabric asserts this signal
when the requested read data has arrived.
(1)
edi_read_master_waitrequest In
edi_read_master port Avalon-MM waitrequest signal.
The system interconnect fabric asserts this signal to cause
the master port to wait.
(1)
ma_read_master_address Out
ma_read_master port Avalon-MM address bus. This bus
specifies a byte address in the Avalon-MM address
space.
(1)
ma_read_master_read Out
ma_read_master port Avalon-MM read signal. The
MegaCore function asserts this signal to indicate read
requests from the master to the system interconnect
fabric.
(1)
ma_read_master_burstcount Out
ma_read_master port Avalon-MM burstcount signal.
This signal specifies the number of transfers in each
burst.
(1)
ma_read_master_readdata In
ma_read_master port Avalon-MM readdata bus. These
input lines carry data for read transfers.
(1)
ma_read_master_readdatavalid In
ma_read_master port Avalon-MM readdatavalid
signal. The system interconnect fabric asserts this signal
when the requested read data has arrived.
