The value is a table in the same format as PSKEY_TEMPERATURE_VS_DELTA_INTERNAL_PA. The values of
the table (even-numbered 16-bit words) in this case are an adjustment applied separately to both the top nybbles of
PSKEY_TX_FILTER_CONFIG
when transmitting the payload of a packet at Enhanced Data Rate; hence they must
lie in the range -15 to 15. The adjusted nybbles will be limited to the range 0 to 15.
Note that, using the default values, there is a discontinuity in the values in this key at 55 deg C, which corresponds
to switching off the TX IF attenuator (see PSKEY_MR_TX_IF_ATTEN_OFF_TEMP
). Since BlueCore can only
measure temperatures at a resolution of 1 deg C, this is represented by two consecutive values at 54 and 55 deg C.

The value is a table in the same format as PSKEY_TEMPERATURE_VS_DELTA_INTERNAL_PA. The values
of the table (even-numbered 16-bit words) in this case are an adjustment applied separately to both the top nybbles
of PSKEY_TX_FILTER_CONFIG
when transmitting the header of a packet at Enhanced Data Rate; hence they
must lie in the range -15 to 15. The adjusted nybbles will be limited to the range 0 to 15.
