controlled by the LPC47M172.

LATCHED_BF_CUT
t1
t2
Periods t1 and t2 should be guaranteed by the inherent design of the system. These timings are not
controlled by the LPC47M172.
There are two possible timing sequences following the power up signal sequencing. The first possible
sequence is with nSLP_S5 staying high and nBACKFEED_CUT transitioning from low to high, remaining
high for an undetermined period and then going back to low. At this point, the system returns to the end of
the power-up sequence.
During these nBACKFEED_CUT transitions, the propagation delays, rise and fall times for
LATCHED_BF_CUT are as described in the figure below. The first sequence can start at the end of the
power-up sequence at any time.
