CCA_ED_THRES
7
R/W
An ED value above the threshold signals a busy channel during a
CCA_ED measurement.
Table 8-9.
0x09 - CCA_THRES
Note:
CCA_ED_THRES: The CCA_ED request will indicate a busy channel, if the measured receive power
is above -91 dBm + 2*CCA_ED_THRES[dB].

IRQ_MASK
255
R/W
Mask register for IRQs.
If bit is set to high, then the IRQ is enabled.
If bit is set to low, then the IRQ is disabled.
IRQ_MASK[7] corresponds to IRQ_7.
IRQ_MASK[0] corresponds to IRQ_0.
Table 8-10.
0x0E - IRQ_MASK
Note:
The occurrence of an interrupt will be signaled over the IRQ wire.
