Pin PWR_ON
Figure 12-3. Timing Flow Pin N_PWR_ON, Status Bit N_Power_On
To switch the transceiver from OFF to IDLE mode, pin PWR_ON must set to 1 (minimum
0.8
positive edge and switches on DVCC and AVCC.
If V
sets the status bit Power_On to 1, an interrupt is issued (T
pin CLK is available.
If the level on pin PWR_ON was set to 0 before the interrupt is issued, the transceiver stays in
OFF mode.
If the transceiver is in any of the active modes (IDLE, RX, RX_Polling, TX, FD), a positive edge
on pin PWR_ON sets Power_On to 1 (after T
generates an interrupt. If Power_On is still 1 during the positive edge on pin PWR_ON, no inter-
rupt is issued. Power_On and the interrupt is deleted after reading the status register.
