Description
WUC timer reload value, Bits[7:0] of [15:0]. A wake-up event is triggered
when the WUC unit is enabled and the timer has counted down to 0. The
timer is clocked with the prescaler output rate. See Table 101.
Description
1: enable
0: disable RCOSC32K calibration
1: reset the WUC_TMR_PRIM_TOFLAG and WUC_PORFLAG bits (Address
0x311, see Table 102)
0: normal operation
Description
Reserved
1: RCOSC32K calibration exited with error
0: without error (only valid if WUC_RCOSC_CAL_EN = 1)
1: RCOSC32K calibration finished
0: in progress (only valid if WUC_RCOSC_CAL_EN = 1)
1: XOSC32K oscillator has settled
0: not settled (only valid if WUC_XOSC32K_EN = 1)
Output signal of the XOSC32K oscillator (instantaneous)
1: chip cold start event has been registered
0: not registered
1: WUC timeout event has been registered
0: not registered (the output of a latch triggered by a timeout event)
1: WUC timeout event is present
0: not present (this bit is set when the counter reaches 0; it is not latched)
Description
Receive input power. After reception of a packet, the RSSI_READBACK value
is valid. RSSI (dBm) = RSSI_READBACK – 107.
Description
Limits the AFC pull-in range. Automatically set by the communications
processor on transitioning into the PHY_RX state. The range is set equal to
half the IF bandwidth. Example: IF bandwidth = 200 kHz, AFC pull-in range =
±100 kHz (MAX_AFC_RANGE = 100).
