TDI I 13 Test data in for JTAG boundary scan. Internally pulled up. Unused in normal operation; connect to either high or low static level. TDO O 121 Test data out for JTAG boundary scan. Unused in normal operation. RNGOSC I 113 Optional random number generator oscillator. Internally grounded. It can be Ex-ORed with internal oscillator to provide random number source. Don’t Connect The pins used for product testability and not used by customers. Leave them unconnected: 2, 3, 11, 82, 83, 86, 87, 91, 112, 114, 141. All other pins are No Connects, and can be left floating or connected.
