JTAG Instruction
I/O Reconfiguration
Use the CONFIG_IO instruction to reconfigure the I/O configuration shift register
(IOCSR) chain. This instruction allows you to perform board-level testing prior to
configuring the Cyclone III device family or waiting for a configuration device to
complete configuration. After the configuration is interrupted and JTAG testing is
complete, the part must be reconfigured using the PULSE_NCONFIG JTAG
instruction or by pulsing the nCONFIG pin low.
You can issue the CONFIG_IO instruction any time during user mode. The
CONFIG_IO instruction cannot be issued when nCONFIG pin is asserted low (during
power up) or immediately after issuing a JTAG instruction that triggers
reconfiguration. For more information about the wait-time for issuing the CONFIG_IO
instruction, refer to
When using CONFIG_IO instruction, you must meet the following timing restrictions:

Table 9–18. Wait Time for Issuing the CONFIG_IO Instruction
Use the ACTIVE_DISENGAGE instruction with CONFIG_IO instruction to interrupt
configuration.
CONFIG_IO usage scenarios.
Wait time after the nCONFIG pin is released
Wait time after PULSE_NCONFIG or ACTIVE_ENGAGE is
issued
CONFIG_IO instruction cannot be issued during the nCONFIG pin low
Observe 230 μs minimum wait time after any of the following conditions are met:
■
■
■
Wait 230 μs after power up with nCONFIG pin high before issuing the CONFIG_IO
instruction (or wait for the nSTATUS pin to go high)
nCONFIG pin goes high

Issuing the ACTIVE_ENGAGE instruction, before issuing the CONFIG_IO
instruction
