Device Reset (5 V Tolerant Input with Internal Pull-up)
This input (active LOW) asynchronously applies reset and synchronously
releases reset to the device. In the reset state, the outputs LSTo0-7 and
BSTo0-7 are set to a HIGH or high impedance state, depending on the state
of the LORS and BORS external control pins, respectively. The assertion of
this pin also clears the device registers and internal counters. Refer to
Section 7.3 on page 24 for the timing requirements regarding this reset
signal.
Test Clock (5 V Tolerant Input)
Provides the clock to the JTAG test logic.
Test Mode Select (5 V Tolerant Input with Internal Pull-up)
JTAG signal that controls the state transitions of the TAP controller.
Test Serial Data In (5 V Tolerant Input with Internal Pull-up)
JTAG serial test instructions and data are shifted in on this pin.
Test Serial Data Out (5 V Tolerant Three-state Output)
JTAG serial data is output on this pin on the falling edge of TCK. This pin is
held in a high impedance state when JTAG is not enabled.
Test Reset (5 V Tolerant Input with Internal Pull-up)
Asynchronously initializes the JTAG TAP controller to the Test-Logic-Reset
state. This pin must be pulsed LOW during power-up for JTAG testing. This
pin must be held LOW for normal functional operation of the device.
Power Supply for Periphery Circuits: +3.3 V
Power Supply for Core Circuits: +1.8 V
Power Supply for Analog PLL: +1.8 V
