Turn on crystal oscillator core

MAIN: CORE_PD = 0

Wait 2 ms*

Turn on bias generator

BIAS_PD = 0

Wait 200

µs

Power Down

*Time to wait depends on the crystal frequency

and the load capacitance

Turn on TX:

PA_POW = 00h

MAIN: F_REG = 1

FS_PD = 0

Wait 250

µs

TX mode

Turn off TX:

PA_POW = 00h

MAIN: TX_PD = 1, FS_PD = 1,

CORE_PD=1, BIAS_PD=1

Power Down

TX_PD = 0

PA_POW = ‘Output power’

Wait 20

µs

Waiting for the PLL to lock

Waiting for the PA to ramp up
