Description
Bits[7:0] of [15:0] of an internal 16-bit count of the number of wake-ups
(WUC timeouts) the device has gone through. It can be initialized to 0x0000.
See Table 53.
Description
Bits[15:8] of [15:0] of an internal 16-bit count of the number of WUC wake-ups
the device has gone through. It can be initialized to 0x0000. See Table 52.
Description
Bits[7:0] of [15:0] (see Table 55). The threshold for the number of wake-ups
(WUC timeouts). It is a 16-bit count threshold that is compared against the
NUMBER_OF_WAKEUPS bits. When this threshold is exceeded, the device
wakes up in the PHY_OFF state and optionally generates
INTERRUPT_NUM_WAKEUPS.
Description
Bits[15:8] of [15:0] (see Table 54).
Description
When the WUC is used and SWM is enabled, the radio powers up and
enables the receiver on the channel defined in the BBRAM and listens for
this period of time. If no preamble pattern is detected in this period, the
device goes back to sleep.
Description
Units of time used to define the RX_DWELL_TIME time period.
A value of 0x33 gives a clock of 995.7 Hz or a period of 1.004 ms.
Description
This sets the RSSI threshold when in smart wake mode with RSSI detection
enabled.
