Reserved
This bit is reserved and should be written with zero.
The Channel register (Reg 0x21) is used to determine the Synthesizer frequency. A value of 2 corresponds to a communication
6:0
Channel
frequency of 2.402 GHz, while a value of 79 corresponds to a frequency of 2.479GHz. The channels are separated from each
other by 1 MHz intervals.
Limit application usage to channels 2-79 to adhere to FCC regulations. FCC regulations require that channels 0 and 1 and
any channel greater than 79 be avoided. Use of other channels may be restricted by other regulatory agencies. The application
MCU must ensure that this register is modified before transmitting data over the air for the first time.

These bits are reserved. This register is read-only.
7:6 Reserved

Valid
The Valid bit indicates whether the RSSI value in bits [4:0] are valid. This register is Read Only.
1 = RSSI value is valid
0 = RSSI value is invalid
The Receive Strength Signal Indicator (RSSI) value indicates the strength of the received signal. This is a read only
4:0 RSSI
value with the higher values indicating stronger received signals meaning more reliable transmissions.

PA Bias
The Power Amplifier Bias (PA Bias) bits are used to set the transmit power of the IC through increasing (values up to 7) or
decreasing (values down to 0) the gain of the on-chip Power Amplifier. The higher the register value the higher the transmit
power. By changing the PA Bias value signal strength management functions can be accomplished. For general purpose
communication a value of 7 is recommended.
Note:
7.
The RSSI will collect a single value each time the part is put into receive mode via Control register (Reg 0x03, bit 7=1). See Section 4.7 for more details.
