NOTES:

1. J3, J5, and R5 do not have to be directly connected to VDD as long as the input voltage is ≥ VIH.

2. G4 and A4 are reserved for future 8M and 16M respectively.

3. These pins are NC for the "S" version or the JTAG signal listed for the "SA" version.

4. TRST is offered as an optional JTAG reset if required in the application. If not needed, can be left floating and will internally be pulled to VDD.

5. Pin T7 does not have to be connected directly to VSS as long as the input voltage is ≤ VIL; on the latest die revision this pin supports ZZ (sleep mode).
