Notes
1. Pin type: I = input, O = output, S = supply.
2. In accordance with the "IEEE1149.1" standard the pins TDI, TMS, TCK and TRST are input pins with an internal
pull-up resistor and TDO is a 3-state output pin.
3. Pins FSVGC, VSVFC, CBO, HSVGC and TTXRQ_XCLKO2 are used for bootstrapping; see Section 7.1
4. For board design without boundary scan implementation connect TRST to ground.
5. This pin provides easy initialization of the Boundary Scan Test (BST) circuit. TRST can be used to force the Test
Access Port (TAP) controller to the TEST_LOGIC_RESET state (normal operation) at once.
