This register provides the ability to override some automatic features of the device.
Bit 7
When this bit is set, the device uses the receive synthesizer frequency rather than the transmit synthesizer frequency for the
given channel when automatically entering transmit mode.
Bit 6
Force Preamble. When this bit is set, the device transmits a continuous repetition of the preamble pattern (see
PREAMBLE_ADR) after TX GO is set. This mode is useful for some regulatory approval procedures. Firmware should set bit
RST of MODE_OVERRIDE_ADR to exit this mode.
Bit 5
Reserved. Must be zero.
Bit 4
Transmit ACK Packet. When this bit is set, the device sends an ACK packet when TX GO is set.
Bit 3
ACK Override. Use TX_CFG_ADR to determine the data rate and the CRC16 used when transmitting an ACK packet.
Bit 2
Disable Transmit CRC16. When set, no CRC16 field is present at the end of transmitted packets.
Bit 1
Reserved. Must be zero.
Bit 0
TX Data Invert. When this bit is set the transmit bitstream is inverted.

Reserved. Must be zero.
Bit 3
Crystal Startup Delay. Setting this bit, sets the crystal startup delay to 150
μ
s to handle warm restarts of the crystal. Firmware
MUST set this bit during initialization.
