Revision X2
Only useful from BlueCore3.
A value of 4 in PSKEY_RX_ATTEN_BACKOFF
implies PSKEY_RX_ATTEN_UPDATE_RATE must
be at least 2: if one key is changed, the other should be changed in direct proportion.
Key Name Key Number Type Default Setting
PSKEY_RX_ATTEN_BACKOFF 0x03ca uint16 4
The back-off value of the attenuation used by the receiver as a difference between the final attenuation
selected by AGC for one packet and the initial attenuation selected for the following packet from the same
remote transmitter.
Only useful from BlueCore3.
There is a dependency betwen this key and PSKEY_RX_ATTEN_UPDATE_RATE
which must be
maintained for correct operation of the AGC: see the description of
PSKEY_RX_ATTEN_UPDATE_RATE
for details.
Key Name Key Number Type Default Setting
PSKEY_ONCHIP_HCI_CLIENT 0x03cc bool 0
This key controls the routing of HCI traffic. For a vanilla 'HCI' firmware build this key should be set to
FALSE (0). For a firmware build that incorporates upper stack layers, this key should be set to TRUE (1).
Key Name Key Number Type Default Setting
PSKEY_INITIAL_BOOTMODE 0x03cd int16 none
The firmware is capable of switching between a number of different 'bootmodes'. Each bootmode presents
a different view of the persistent store, with some keys being overridden by bootmode-specific values. A
device can support a maximum of 8 bootmodes. If this key is present the device will enter the specified
bootmode after a cold reset. If the key is not present, bootmode 0 will be used.

Number
Type Default Setting
PSKEY_RADIOTEST_CDMA_LO_REF_LIMITS 0x03ce uint16 0x2314
Used in an identical way to PSKEY_CDMA_LO_REF_LIMITS, except in radiotest mode.
Key Name Key
Number
Type Default Setting
PSKEY_RF_TRAP_BAD_DIVISION_RATIOS 0x03cf uint16 0
This PSKEY enables code to trap the frequency division ratios that cause unwanted effects.
When creating the lookup table for RF oscillations, certain entries can create spurs at 1.8 GHz. Bits 0 and 1
control this.
Bit 0 should be turned on or off to enable or disable trapping of such ratios on transmission.
Bit 1 should be turned on or off to enable or disable trapping of such ratios on reception.
