JTAG Instruction
9–20:
ACTIVE_DISENGAGE
The ACTIVE_DISENGAGE instruction places the active configuration controller (AS
and AP) into an idle state prior to JTAG programming. The active configuration
controller is the AS controller when the MSEL pins are set to AS configuration scheme
and the AP controller when the MSEL pins are set to the AP configuration scheme.
The two purposes of placing the active controllers in an idle state are:
■
■
The ACTIVE_DISENGAGE instruction is required before JTAG programming
regardless of the current state of the Cyclone III device family if the MSEL pins are set
to an active configuration scheme (AS or AP). If the ACTIVE_DISENGAGE instruction
is issued during a passive configuration scheme (PS or FPP), it has no effect on the
Cyclone III device family. Similarly, the CONFIG_IO instruction is issued after an
ACTIVE_DISENGAGE instruction, but is no longer required to properly halt
configuration.
for each configuration mode. The ordering of the required instructions is a hard
requirement and must be met to ensure functionality.
In AS or AP configuration schemes, the ACTIVE_DISENGAGE instruction puts the
active configuration controllers into idle state. If a successful JTAG programming is
executed, the active controllers are automatically re-engaged after user mode is
reached using JTAG programming. This causes the active controllers to transition to
their respective user mode states.
To ensure that they are not trying to configure the device in their respective
configuration modes during JTAG programming
To allow the controllers to properly recognize a successful JTAG programming
that results in the device reaching user mode
