Functional Description
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 cycle is terminated. The reset status bits are
latched (7) and reset processing waits for the external RESET pin to negate (8).
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).
10.4.3.2 Reset Status Flags
For a POR reset, the POR bit 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 RESET pin not asserted
and no SOFT or WDR event, then the LOC and/or LOL bits are the only bits set.
