Description
write_param
Input
No
Write signal for parameter specified in
param[]
and with value specified in
data_in[]
.
Signal indicating parameter specified with
param[]
should be written into remote update
block with the value specified in
data_in[]
. The
number of bits read from
data_in[]
depends on
the parameter type.
The signal is sampled at the rising clock edge.
The signal should be asserted for only one clock
cycle to prevent the parameter from being
rewritten on a subsequent clock cycle. The busy
signal is activated as soon as
write_param
is read
as being active. While the parameter is being
written, the busy signal remains asserted, and
input to
data_in[]
is ignored. When the busy
signal is deactivated, another parameter can be
written. This signal is only valid in Factory
configuration mode because parameters cannot
be written in Application configuration mode.
The signal cannot be used in local update mode.
param[]
Input
No
Bus that specifies which parameter need to be
read or updated.
A 3-bit bus that selects the parameter to be read
or updated. If left unconnected, the default value
for this port is 000.
