The CONFIG_IO instruction does not hold the nSTATUS pin low until
reconfiguration. You must disengage the active configuration controllers (AS and AP)
by issuing the ACTIVE_DISENGAGE and ACTIVE_ENGAGE instructions when the
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
controllers into the idle state. The active configuration controller is re-engaged after
user mode is reached using 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 the
nCONFIG pin 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
the reconfiguration in configuration modes; therefore, it is not necessary to pull the
nCONFIG pin low or issue the PULSE_NCONFIG instruction.
