Description
reset_timer
Input
No
Reset signal for watchdog timer.
Signal indicating the internal watchdog timer should
be reset. Unlike other inputs, this signal is not
affected by the busy signal and can reset the timer
even when busy is asserted.
A falling edge of this signal triggers a reset of the user
watchdog timer.
This signal cannot be used in local update mode.
For the timing specification of this parameter, refer to
the specific device handbook.
clock
Input
Yes
Clock input to the remote update block.
Clock input to control the machine and to drive the
remote update block during the update of parameters.
This port must be connected to a valid clock.
reset
Input
Yes
This is an active high signal. Asserting this signal high
will reset the IP core.
Asynchronous reset input to the IP core to initialize
the machine to a valid state. The machine must be
reset before first use, otherwise the state is not
guaranteed to be valid.
busy
Output
No
Busy signal that indicates when remote update block
is reading or writing data.
While this signal is asserted, the machine ignores
most of its inputs and cannot be altered until the
machine deasserts this signal. Therefore, changes are
made only when the machine is not busy.
This signal goes high when
read_param
or
write_
param
is asserted, and remains high until the read or
write operation completes.
