connected to bidirectional differential antenna pins (RFP, RFN), so that no external
antenna switch is needed.
In Basic Operating Mode a transmission is started from PLL_ON state by either writing
TX_START to register bits TRX_CMD (register 0x02, TRX_STATE) or by raising edge
of SLP_TR.
In Extended Operating Modes a transmission is started automatically dependent on the
transaction phase of either RX_AACK or TX_ARET, refer to section 7.2.
The RF output power can be set via register bits TX_PWR in register 0x05
(PHY_TX_PWR). The maximum output power of the transmitter is typical +3 dBm. The
selectable output power range of the transmitter is 20 dB.
Register 0x05 (PHY_TX_PWR)
The PHY_TX_PWR register sets the transmit power and controls the FCS algorithm for
TX operation.
• Bit 7 – TX_AUTO_CRC_ON
Refer to sections 7.2.6 and 8.2.
• Bit [6:4] – Reserved
• Bit [3:0] – TX_PWR
The register bits TX_PWR sets the TX output power of the AT86RF230. The available
power settings are summarized in Table 9-1.
