Table
8–14:

The CONFIG_IO instruction does not hold nSTATUS low until reconfiguration. You
must disengage the AS or AP configuration controller by issuing the
ACTIVE_DISENGAGE and ACTIVE_ENGAGE instructions when active configuration is
interrupted. You must issue the ACTIVE_DISENGAGE instruction alone or prior to the
CONFIG_IO instruction if the JTAG_PROGRAM instruction is to be issued later
(Table
active configuration controller is re-engaged after user mode is reached through JTAG
programming
While executing the CONFIG_IO instruction, all user I/Os are tri-stated.
If reconfiguration after interruption is performed using configuration modes (rather
than using JTAG_PROGRAM), it is not necessary to issue the ACTIVE_DISENGAGE
instruction prior to CONFIG_IO. You can start reconfiguration by either pulling
nCONFIG low for at least 500 ns or issuing the PULSE_NCONFIG instruction. If the
ACTIVE_DISENGAGE instruction was issued and the JTAG_PROGRAM instruction fails
to enter user mode, you must issue the ACTIVE_ENGAGE instruction to reactivate the
active configuration controller. Issuing the ACTIVE_ENGAGE instruction also triggers
reconfiguration in configuration modes; therefore, it is not necessary to pull nCONFIG
low or issue the PULSE_NCONFIG instruction.
ACTIVE_DISENGAGE
The ACTIVE_DISENGAGE instruction places the active configuration controller (AS
and AP) into an idle state prior to JTAG programming. The two purposes of placing
the active controller in an idle state are:

To ensure that it is not trying to configure the device during JTAG programming
