TDO

Test Data Out.

3.3V LVTTL

TMS

Test Mode Select.

3.3V LVTTL

w/pull-up

TRST

Test Reset. During chip power-up, this signal must be low from the

start of VDD ramp-up until at least 16 SysClk cycles after VDD is

stable in order to initialize the JTAG controller.

3.3V LVTTL

w/pull-up

Signal Functional Description (Sheet 6 of 8)

Notes:

1. Receiver input has hysteresis

2. Must pull up (recommended value is 3k

Ω to 3.3V)

3. Must pull down (recommended value is 1k

Ω)

4. If not used, must pull up (recommended value is 3k

Ω to 3.3V)

5. If not used, must pull down (recommended value is 1k

Ω)

6. Strapping input during reset; pull-up or pull-down required
