On all Cyclone III device family in the chain, nCE must be driven low by connecting it to ground, pulling it
low using a resistor or driving it by some control circuitry. For devices that are also in multi-device AS, AP,
PS, or FPP configuration chains, the nCE pins must be connected to GND during JTAG configuration or
JTAG configured in the same order as the configuration chain.
On all Cyclone III device family in the chain, nCEO is left floating or connected to the nCE of the next
device.
These pins must not be left floating. These pins support whichever non-JTAG configuration that is used in
production. If you only use JTAG configuration, tie these pins to GND.
Driven high by connecting to the V
resistor or driven high by some control circuitry.

indicates successful configuration.
Must not be left floating. Drive low or high, whichever is more convenient on your board.
When programming a JTAG device chain, one JTAG-compatible header is connected
to several devices. The number of devices in the JTAG chain is limited only by the
drive capability of the download cable. When four or more devices are connected in a
JTAG chain, Altera recommends buffering the TCK, TDI, and TMS pins with an
on-board buffer.
JTAG-chain device programming is ideal when the system contains multiple devices,
or when testing your system using JTAG BST circuitry.
