WISP_init()

void WISP_init

(

void

)

Called by client code as a first step after PUC.

void WISP_init (void)

Purpose

Postcondition

the RAM, clock and peripherals are initialized for use

Timing

1. The routine is entered X cycles into the CPU's operation.
2. The routine tries to sleep Y cycles into the CPU's operation.
3. From a cold-boot, the CPU is configured for fCPU = Z MHz. (i.e. ...?)

Considerations

1. If preforming a 'sleep_till_full_power' operation,

TODO: enable PIN_RX_EN only when needed in the future
