For proper operation of the CC330xMOD module, perform the recommended
power-up sequencing as follows:
- All supplies (1V8_IN, 3V3_IN, VPP) must be available before nReset is released.
- For an external slow clock, confirm that the
clock is stable before nReset is deasserted
(high).
- The nReset pin must be held low for at least
10μs after the stabilization of the external power
supplies.
