Description
64 chip PN code, SDR mode, PA = 6
AGC is enabled. LNA and attenuator are disabled. Fast turnaround is disabled,
the device uses high side receive injection and Hi-Lo is disabled. Overwrite to
receive buffer is enabled and RX buffer is configured to receive eight bytes
maximum. Enables RXOW to allow new packets to be loaded into the receive
buffer. This also enables the VALID bit which is used by the first generation
radio’s error correction firmware.
AutoACK is disabled. Forcing end state is disabled. The device is configured to
transition to Idle mode after Receive or Transmit. ACK timeout is set to 128 µs.
All SOP and framing features are disabled. Disable LEN_EN=0 if EOP is
needed.
Disable Transmit CRC-16.
The receiver rejects packets with a zero seed. The RX CRC-16 checker is
disabled and the receiver accepts bad packets that do not match the seed in
the CRC_seed registers. This helps in communication with the first generation
radio that does not have CRC capabilities.
Set ALL SLOW. When set, the synthesizer settle time for all channels is the
same as the slow channels in the first generation radio, for manual ACK
consistency
Sets the number of allowed corrupted bits to 7 which is close to the recom-
mended 12% value.
Sets the number of consecutive symbols for non-correlation to detect end of
packet.
AAAA are the two preamble bytes. Any other byte can also be written into the
preamble register file. Recommended counts of the preamble bytes to be sent
must be >8.
