TEST DATA OUTPUT is the serial output pin for JTAG. TDO is driven on the falling
edge of TCK during the SHIFT-IR and SHIFT-DR states of the Test Access Port. At
other times, TDO floats. TDO does not float during ONCE mode.
TEST RESET asynchronously resets the Test Access Port (TAP) controller function
of IEEE 1149.1 Boundary Scan testing (JTAG). When using the Boundary Scan
feature, connect a pull-down resistor between this pin and V
used, this pin must be connected to V
Section 4.3, “Connection Recommendations” on page
TEST MODE SELECT is sampled at the rising edge of TCK to select the operation of
the test logic for IEEE 1149.1 Boundary Scan testing.
POWER pins intended for external connection to a V
PLL POWER is a separate V

add a simple bypass filter circuit to reduce noise-induced clock jitter and its effects on
timing relationships.
5 V REFERENCE VOLTAGE input is the reference voltage for the 5 V-tolerant I/O
buffers. This signal should be connected to +5 V for use with inputs which exceed
3.3 V. When all inputs are from 3.3 V components, this pin should be connected to
3.3 V.
GROUND pins intended for external connection to a V
NO CONNECT pins. Do not make any system connections to these pins.
EXTERNAL INTERRUPT pins are used to request interrupt service. The XINT[7:0]#
pins may be configured in three modes:
Dedicated Mode: Each pin is assigned a dedicated interrupt level. Dedicated inputs
may be programmed to be level (low) or edge (falling) sensitive.
Expanded Mode: All eight pins act as a vectored interrupt source. The interrupt pins
are level sensitive in this mode.
Mixed Mode: The XINT[7:5]# pins act as dedicated sources and the XINT[4:0]# pins
act as the five most significant bits of a vectored source. The least significant bits of
the vectored source are set to 010
Unused external interrupt pins should be connected to V
NON-MASKABLE INTERRUPT causes a non-maskable interrupt event to occur.
NMI# is the highest priority interrupt source and is falling edge-triggered. when NMI#
is unused, it should be connected to V
