Revision X2
This key works in consort with PSKEY_SLOW_CLOCK_TEMP_HYSTERESIS. See the description of
that key for the full description.
The units of this key are degrees Celsius.
Key Name Key Number Type Default Setting
PSKEY_RX_MR_CONFIGS 0x21b9 uint16[] 0x1A17, 0x0001
A set of values used for configuring certain registers for optimum EDR operation.
Only to be set on advice from CSR.
(The abbreviation MR for Medium Rate is used consistently in place of EDR for Enhanced Data Rate
throughout the PS keys as many were introduced before the abbreviation EDR came into use.)

PSKEY_PIO_DEEP_SLEEP_EITHER_LEVEL 0x21bd uint32 0
Allows the chip to deep sleep irrespective of the level of the PIO lines. Traditionally BlueCore chips will
stay out of deep sleep when any PIO line configured as an input is high. This behaviour can be modified by
setting PSKEY_PIO_WAKEUP_STATE
so that the chip will stay out of deep sleep when lines are low, but
enter deep sleep when the lines are high.
Each bit in this PSKEY corresponds to a PIO line from 0 to 31. Note that 31 PIOs may not be present on all
BlueCores. Setting a bit will result that PIO's level having no effect on the chip's deep sleep behaviour; the
chip will go into deep sleep if the PIO is high or low. The BlueCore will still wakeup to process changes in
PIO levels.
The PIO lines must already have been configured to wake the chip using either
PSKEY_DEEP_SLEEP_PIO_WAKE
or the VM.
