NOTES:
1. H1, H2, and N7 do not have to be directly connected to V
2. A9, B9, B11, A1, R2 and P2 are reserved for future 9M, 18M, 36M, 72M, 144M, and 288M respectively respectively.
3. These pins are NC for the "S" version and 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 V
5. Pin H11 supports ZZ (sleep mode) on the latest die revision.
