The power-on procedure to P_ON state is shown in
Figure 7-3.
When the external supply voltage (V
ceiver enables the crystal oscillator (XOSC) and the internal 1.8 V voltage regulator for the
digital domain (DVREG). After t
(CLKM) at default rate of 1 MHz. If CLKM is available the SPI is already enabled and can be
used to control the transceiver. As long as no state change towards state TRX_OFF is per-
formed the radio transceiver remains in P_ON state.
