Interrupt Polarity
0
0 = Active low
1 = Active high
Interrupt Enable. If interrupt is disabled, pending interrupts
are not cleared and the INT pin deasserts. INTEN is a
0
global setting to mask all interrupts.
0 = Interrupt disabled
1 = Interrupt enabled
Opens/Closes USB Switch
0
0 = Switch open
1 = Switch closed
Charge-Pump Enable
0
0 = Charge pump disabled
1 = Charge pump enabled
Low-Power Mode
0 = Low-power mode disabled; oscillator/bandgap always on
1
1 = Low-power mode enabled; oscillator/bandgap turned
off under the following conditions: no V_BUS, USBSWC = 0,
and CP_ENA = 0
Charger-Type Source-Detection Time
0
0 = DCHK, tDP_SRC_ON = 40ms
1 = DCHK, t_{DP_SRC_ON} = 625ms
Charger-Type Manual-Detection Enable. Set CHG_TYP_M
to 1 to force the internal logic to open the USB switches
0
and perform a charger-type detection. After the detection
state matching completes, this bit resets to 0.
0 = Charger detection disabled
1 = Force a manual charge detection
