Threshold Low
Description
This bit is reserved and should be written with zero.
The Threshold Low value is used to determine the number of missed chips allowed when attempting to correlate a
single data bit of value ‘0’. A perfect reception of a data bit of ‘0’ with a 64 chips/bit PN code would result in zero
correlation matches, meaning the exact inverse of the PN code has been received. By setting the Threshold Low
value to 0x08 for example, up to eight chips can be erroneous while still identifying the value of the received data
bit. This value along with the Threshold High value determine the correlator count values for logic ‘1’ and logic ‘0’.
The threshold values used determine the sensitivity of the receiver to interference and the dependability of the
received data. By allowing a minimal number of erroneous chips the dependability of the received data increases
while the robustness to interference decreases. On the other hand increasing the maximum number of missed chips
means reduced data integrity but increased robustness to interference and increased range.

Threshold High
The Threshold High value is used to determine the number of matched chips allowed when attempting to correlate
a single data bit of value ‘1’. A perfect reception of a data bit of ‘1’ with a 64 chips/bit or a 32 chips/bit PN code would
result in 64 chips/bit or 32 chips/bit correlation matches, respectively, meaning every bit was received perfectly. By
setting the Threshold High value to 0x38 (64-8) for example, up to eight chips can be erroneous while still identifying
the value of the received data bit. This value along with the Threshold Low value determine the correlator count
values for logic ‘1’ and logic ‘0’. The threshold values used determine the sensitivity of the receiver to interference
and the dependability of the received data. By allowing a minimal number of erroneous chips the dependability of
the received data increases while the robustness to interference decreases. On the other hand increasing the
maximum number of missed chips means reduced data integrity but increased robustness to interference and
increased range.

Wakeup Enable
Wakeup interrupt enable.
0 = disabled
1 = enabled
A wakeup event is triggered when the PD pin is deasserted and once the IC is ready to receive SPI communications.
