0xBFFC0881 ERR_UWPLL_UNLOCKED
For some conditions, when an external reference is
used and the reference source is reapplied (for
example, powered down then back up, or
disconnected then reconnected) a transient may
occur. Reading the error queue should clear this
error.
If the reference is constantly applied and this error
is not cleared when the error is read, this may
indicate a hardware failure. If this error occurs
when an internal reference is selected, this may
also indicate a hardware failure.

0xBFFC0883 ERR_ALC_HIGH_UNLEVELED
This error could occur if power is set above the
maximum specified power level when using
internal leveling. Check to ensure the proper
power level is being requested.
If using external leveling, this could occur if the
power is set above any of the internal maximum
power limits, which could be caused by the
external hardware configuration and power levels
being selected in association with them. Check the
external configuration and ensure that the
returned power level within the loop and that
being selected are within the proper operational
range of the E6432.
"ALC High-Band
Unleveled Error"
0xBFFC0884 ERR_ALC_LOW_UNLEVELED
This error occurs if power is set below the
minimum specified power level when using
internal leveling. Check to ensure the proper
power level is being requested.
If using external leveling this could occur if the
power is set below any of the internal minimum
power limits which could be caused by the external
hardware configuration and power levels being
selected in association with them. Check the
external configuration and ensure that the
returned power level within the loop and that
being selected are within the proper operational
range of the E6432.
