+The trace from S71PL129NC0 ball D5 (flash reset) goes to a pull-up resistor and
+to a microvia at (5130,717).  On L7 this microvia connects to an inner via at
+(5141,681).  Found it on L2, trace from inner via goes to a microvia to L1 at
+(4676,922).  On L1 the trace goes to a pair of resistor footprints, the left
+one is populated, the right one is not.  Tracing the populated branch: the
+trace goes to a microvia at (4516,1047).  On L2 the microvia connects to an
+inner via at (4540,1032).  Found it on L4, the trace goes through another inner
+via at (3718,1052) and finally to yet another inner via at (1699,1348).

+Tracing the populated branch from (1699,1348): found it on L2, goes to a
+microvia back to L1 at (1673,1352).  It is TCXOEN!
+
+Tracing the unpopulated resistor branch: microvia from L1 to L2 at (4665,892).
+On L2 the trace goes two ways: to another microvia back to L1 at (4142,802) and
+to an inner via at (5150,834).  The microvia back to L1 at (4142,802) falls on
+Calypso ball F4 - that's FDP!  Tracing the inner via at (5150,834): found it on
+L7, trace obscured by damage, apparently ends at (5169,751), there may have
+been a microvia around (5166,709).  It might be plausibly connected to the
+WP#/ACC pin, which is also pulled up like RST#, but the damage makes it
+impossible to trace for certain.
