Description
reconfig_address[log2<N>+18:0]
Input
reconfig_clk
Address bus. The lower 19
bits specify address, and
the upper bits specify the
channel.
reconfig_writedata[7:0]
Input
reconfig_clk
An 8-bit data write bus.
Data to be written into the
address indicated by
reconfig_address
.
reconfig_readdata[7:0]
Output
reconfig_clk
An 8-bit data read bus.
Valid data is placed on this
bus after a read operation.
Signal is valid after
reconfig_waitrequest
goes high and then low.
reconfig_waitrequest
Output
reconfig_clk
A one-bit signal that
indicates that the AVMM
interface is busy. Keep the
AVMM command asserted
until the interface is ready
to proceed with the read/
write transfer.
When Share reconfiguration interface is disabled and Provide separate
interface for each channel is enabled, the Native PHY IP core provides an
independent reconfiguration interface for each channel. For example, when a
reconfiguration interface is not shared for a four-channel Native PHY IP instance,
reconfig_address_ch0[18:0]
corresponds to the reconfiguration address bus of
logical channel 0,
reconfig_address_ch1[18:0]
correspond to the
reconfiguration address bus of logical channel 1,
reconfig_address_ch2[18:0]
corresponds to the reconfiguration address bus of logical channel 2, and
reconfig_address_ch3[18:0]
correspond to the reconfiguration address bus of
logical channel 3.
The following figure shows the signals available when the Native PHY is configured for
four channels and the Share reconfiguration interface option is not enabled and
Provide separate interface for each channel is enabled.
Figure 86.
