6.5.3 Data Interpretation
6.5.4 Interrupt Handling
6.5.5 Register Description
8168C-MCU Wireless-02/10
The PHY_ED_LEVEL (ED) is an 8-bit register. The ED value of the AT86RF212 has a
valid range from 0x00 to 0x54 (0 to 84) with a resolution of about 1 dB. Values 0x55 to
0xFE do not occur and a value of 0xFF indicates the reset value.
An ED value of 0 indicates a receiver input power less than or equal to
RSSI_BASE_VAL [dBm] (refer to Table 6-25); a value of 85 indicates an input power
equal to or larger than (RSSI_BASE_VAL + 87) [dBm].
The receiver input power can be calculated as follows:
Figure 6-4. Mapping between ED Value and Receiver Input Power
Interrupt IRQ_4 (CCA_ED_DONE) is issued at the end of a manually initiated ED
measurement.
Note that an ED measurement should only be initiated in RX states but not in
RX_AACK
(CCA_ED_DONE) without actually performing an ED measurement.
Register 0x07 (PHY_ED_LEVEL)
The PHY_ED_LEVEL register contains the result of an ED measurement.
