Description
data_in[]
Input
No
Data input for writing parameter data into the
remote update block. Input bus for parameter
data.
For some parameters, not all bits are used. In this
case, the lower-order bits are used (for example,
status values use bits
[4:0]
).
If left unconnected, this bus defaults to
0
. The
port is ignored if the current configuration is the
Application configuration.
A 22-bit bus width in the Quartus II software
version 13.0 or earlier. For the Quartus II
software version 13.1 and onwards, the bus
widths are as follow:
• 24-bit bus width—using 3-byte addressing
configuration device, for example EPCS128.
• 32-bit bus width—using 4-byte addressing
configuration device, for example EPCQ256.
reconfig
Input
Yes
Signal indicating that reconfiguration of the part
should begin using the current parameter
settings. A value of 1 indicates reconfiguration
should begin. This signal is ignored while busy is
asserted to ensure all parameters are completely
written before reconfiguration begins.
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.
