Type Default Setting
PSKEY_LC_PEER_POWER_DECR_PERIOD 0x0058 TIME 1 * SECOND
The period, measured in microseconds, between attempts to decrement the peer's transmit power, the same
interval is used for measurements of channel quality to support LMP channel quality driven data rate
messages.
This pskey is paired with the respective increment peer power period. This key will have a minimum value
of 100ms, how ever it will be disabled if the increment peer power period is set to 0. This means the local
device will not send messages concerning peer power management.

PSKEY_LC_COMBO_DOT11_PULL_DIRECTION 0x005b uint16 0x0000
This key configures the input lines on some BlueCore chips associated with 802.11 coexistence interfaces.
For each bit set in this PSKEY that corresponds to a coexistence input signal, the corresponding PIO will
be configured with a weak pull-up, otherwise it will be left as a weak pull-down (the default).

Type Default Setting
PSKEY_LC_COMBO_DOT11_PERIODIC_PIO_MASK 0x005c uint16[] none
A two-element array of uint16s specifying the use of PIO lines to signal the timing of very important
periodic activity between BlueCore and a collocated IEEE 802.11 radio:
{ uint16 pio_mask, uint16 pio_invert }
Bits 0 to 15 of "pio_mask" and "pio_invert" map to PIO0 to PIO15 respectively. A bit of "pio_mask" set to
high enables use of the corresponding PIO pin to signal periodic activity. A bit of "pio_invert" set to high
indicates that the corresponding PIO pin is active low instead of active high.
PSKEY_LC_COMBO_DOT11_PERIODIC_PIO_MODE
is used to control how the specified PIOs are
used.

Type Default Setting
PSKEY_LC_COMBO_DOT11_PERIODIC_PIO_MODE 0x005d uint16 COEXISTENCE_BT_OUTPUT
Set the default usage of the periodic PIO coexistence lines specified by
PSKEY_LC_COMBO_DOT11_PERIODIC_PIO_MASK
(if any).
The pskey's acceptable values are:
