Test Reset (TTL compatible). JTAG pin used to initialize the JTAG controller. This pin
is tied low for normal device operation. When pulled high, the JTAG controller is
ready for device testing.
Power supply for digital circuitry. All VDD pins must be connected together as close
to the device as possible. A 0.1 F ceramic capacitor should be connected between
each group of VDD pins and the ground plane as close to the device as possible.
Power supply for 3.3 V digital circuitry. All VDDO pins must be connected together as
close to the device as possible. A 0.1 F ceramic capacitor should be connected
between each group of VDDO pins and the ground plane, as close to the device as
possible.
Power supply for analog circuitry. All VAA pins and VPOS must be connected
together as close to the device as possible. A 0.1 F ceramic capacitor should be
connected between each group of VAA pins and the ground plane as close to the
device as possible.
Ground for digital circuitry. All GND pins must be connected together as close to the
device as possible.
Ground for analog circuitry. All AGND pins and VNEG must be connected together as
close to the device as possible.
