FUNCTIONAL DEVICE OPERATION
OPERATING MODES
POWER MONITORING
threshold is used as a weak battery warning. An interrupt LOBATHI is generated when crossing the threshold (dual edge). The
LOBATL threshold is used as a low battery detect. An interrupt LOBATLI is generated when dropping below the threshold. The
sense bits are coded in line with previous generation parts.

Table 28. BP Detection Thresholds
Notes
45.
The voltage at BPSNS and BP is monitored by detectors as summarized in
The UVDET and BPON thresholds are related to the power on/off events as described earlier in this chapter. The LOBATH
BPSNS1
Default setting for BPSNS[1:0] is 00. The above specified thresholds are ±50 mV accurate for the indicated edge. A hysteresis is applied
to the detectors on the order of 100 mV. BPON is monitoring BP. UVDET, LOBATL and LOBATH are monitoring BPSNS and thresholds
are correlated.

Table 29. Power Monitoring Summary
Time slots may be included for blocks which are defined by the PUMS pin as disabled to allow for
potential activation.
The following supplies are not included in the matrix since they are not intended for activation by the
startup sequencer: VCAM, VGEN1, VGEN3, VVIDEO, and VAUDIO. SWBST is not included on the
PUMS2 = Open column.
USB supply VUSB, is only enabled if 5.0 V is present on UVBUS.
SWBST = 5.0 V powers up and so does VUSB regardless of 5.0 V present on UVBUS. By default
VUSB will be supplied by SWBST.
