TCK - JTAG Test Clock, LQFP Pin 97, BGA Pin F14.

Data on TDI is valid on the rising edge of TCK. Data on TDO is valid on the falling edge of

TCK. When TCK is stopped high or low, the contents of all JTAG registers remain unchanged.

Tie low when not used.

TDO- JTAG Test Data Output, LQFP Pin 98, BGA Pin F13.

TAG test data is shifted out of the device on this pin. Data is output on the falling edge of

TCK. Leave as NC when not used.

TDI- JTAG Test Data Input, LQFP Pin 99, BGA Pin F12.

JTAG test data is shifted into the device using this pin. The pin is sampled on the rising edge

of TCK. TDI is pulled up internally and may be left as a NC when not used.

Miscellaneous

REF - Reference Output, LQFP Pin 94, BGA Pin H13.

This pin must be tied to ground through 13.3 kΩ 1% resistor.

No Connects

NC - No Connects, LQFP Pin 82-83, BGA Pin K13-K14.
