1 =
If "Fallback to Oscillator" is enabled and a fallback has
occurred, the corresponding failure is indicated in the IESTA1
and/or IESTA2 registers. For all clock failures, the PLL bit
("PLL Source Failure Indication", IESTA2 register) as well as
the clock source related bit (in IESTA1 or IESTA2 register) will
be set to "1". With the clock valid again the previously changed
bits in IESTA1 and/or IESTA2 are set back to "0", the fallback
must be disabled (CMD2=01
enabled again thereafter.
