Description
Disable the UVLO for the VDDIO rail and its
comparator (suggested for rail voltages different
to 1.8 V and to save quiescent current)
Power-good configuration for Buck B
0: Power-good signal not masked during
DVC transitions
1: Power-good signal masked during DVC
transitions (keep previous status)
Power-good configuration for Buck A
0: Power-good signal not masked during
DVC transitions
1: Power-good signal masked during DVC
transitions (keep previous status)
Over Current configuration for Buck B
00: Event generation due to over current hit
is always active during DVC transitions of
the Buck converter
01: Event generation due to over current hit is
masked during DVC transitions of the buck
converter + 2 µs extra masking at the end
10: Event generation due to over current hit is
masked during DVC transitions of the buck
converter + 10 µs extra masking at the end
11: Event generation due to over current hit is
masked during DVC transitions of the buck
converter + 50 µs extra masking at the end
Over Current configuration for Buck A
