If a loss-of-clock or loss-of-lock condition is detected during the 512 cycle wait, the reset sequence
continues after a PLL lock (9, 9A).
10.6.3.2 Reset Status Flags
For a POR reset, the POR and LVD bits in the RSR are set, and the SOFT, WDR, EXT, LOC, and LOL
bits are cleared even if another type of reset condition is detected during the reset sequence for the POR.
If a loss-of-clock or loss-of-lock condition is detected while waiting for the current bus cycle to complete
(5, 6) for an external reset request, the EXT, SOFT, and/or WDR bits along with the LOC and/or LOL bits
are set.
If the RSR bits are latched (7) during the EXT, SOFT, and/or WDR reset sequence with no other reset
conditions detected, only the EXT, SOFT, and/or WDR bits are set.
If the RSR bits are latched (4) during the internal reset sequence with the RSTI pin not asserted and no
SOFT or WDR event, then the LOC and/or LOL bits are the only bits set.
For a LVD reset, the LVD bit in the RSR is set, and the SOFT, WDR, EXT, LOC, and LOL bits are cleared
to 0, even if another type of reset condition is detected during the reset sequence for LVD.
