JTAG Clock. This pin shifts data into JTDI on the rising edge and out of JTDO on the
falling edge. JTCLK is typically a low frequency (less than 10MHz) 50% duty cycle clock
signal. If boundary scan is not used, JTCLK should be pulled high. See Section 10.
JTAG Mode Select. This pin is used to control the JTAG controller state machine. JTMS
is sampled on the rising edge of JTCLK. If boundary scan is not used, JTMS should be
left unconnected or pulled high. See Section 10.
JTAG Data Input. This pin is used to input data into the register that is enabled by the
JTAG controller state machine. JTDI is sampled on the rising edge of JTCLK. If boundary
scan is not used, JTDI should be left unconnected or pulled high. See Section 10.
JTAG Data Output. This pin is the output of an internal scan shift register enabled by
the JTAG controller state machine. JTDO is updated on the falling edge of JTCLK. JTDO
is in high-impedance mode when a register is not selected or when the
JTDO goes into and out of high-impedance mode after the falling edge of JTCLK. See
Section 10.
JTAG Reset (Active Low). When active, this pin forces the JTAG controller logic into
the reset state and forces the JTDO pin into high-impedance mode. The JTAG controller
is also reset when power is first applied via a power-on reset circuit.
high or low for normal operation, but must be high for JTAG operation. See Section 10.
