VOUTREG[7..0] Vout Adjustment register $0F
NOTE:
INMDE[7..0] Indicator mode register $10
NTCREG[7..0] External NTC low limit register $11
CNTC: a positive going pulse clears the NTC high temperature limit and clear the STATUS[NTC] bit. The bit shall be Low
to resume NTC normal operation.
NOTE:
NTCBIAS[7..0] NTC current bias register $12
NOTE:
ICHG[7..0] SuperCAP re−charge current register $13
NOTE:
STATUS[7..0] System LED check READ register $17
RDY: Output Capacitor status:
voltage
NTC: external thermal sensor flag
the power blocks are de−activated (Charge pump, flash and
Torch/Video)
READ only
0 ³ Output capacitor not fully charged yet
1 ³ Output capacitor fully charged to the programmed
0 ³ a high temperature has been sensed by the NTC. All
1 ³ normal operation, no high temperature detected.

The Vout voltage must be reduced to the minimum value when the Torch/Video mode is activated: see the Torch/Video paragraph
and the Thermal Consideration note.
a ±15% tolerance applies to each bit of the NTCREG register
a ±10% tolerance, measured at V
TOUTDIS1 & TOUTDIS2: these two bits are used to disconnect the Time Out function when B7 and B6 are High:
