1. b = read/write; r = read only; w = write only; ‘-’ = not used, default value is undefined.
2. SOP_CODE_ADR default = 0x17FF9E213690C782.
3. DATA_CODE_ADR default = 0x02F9939702FA5CE3012BF1DB0132BE6F.
4. PREAMBLE_ADR default = 0x333302. The count value must be great than 4 for DDR and greater than 8 for SDR
5. Registers must be configured or accessed only when the radio is in IDLE or SLEEP mode. The PMU, GPIOs, and RSSI registers can be accessed in Active Tx and
6. EOP_CTRL_ADR[6:4] must never have the value of “000”, that is, EOP Hint Symbol count must never be “0”
7. PFET Bit: Setting this bit to "1" disables the FET, therefore safely allowing Vbat to be connected to a separate reference from Vcc when the PMU is disabled to the radio.
