Thermal Warning hysteresis
0 = 8 degrees C
1 = 16 degrees C
Thermal Warning temperature
00 = 90 degrees C
01 = 100 degress C
10 = 110 degrees C
11 = 120 degrees C
Indicates whether the system is ON or OFF.
0 = OFF
1 = ON (or SLEEP)
OFF can be commanded by writing CHIP_ON = 0.
Note that writing CHIP_ON = 1 is not a valid ‘ON’
event, and will not trigger an ON transition.
Indicates whether the system is in the SLEEP state.
0 = Not in SLEEP
1 = SLEEP
WAKE can be commanded by writing CHIP_SLP = 0.
SLEEP can be commanded by writing CHIP_SLP = 1.
Low Power Voltage Reference Control
0 = Normal
1 = Low Power Reference Mode select
Note that Low Power Reference Mode is only
supported when the Auxiliary ADC is disabled.
Power State transition delay
00 = No delay
01 = No delay
10 = 1ms
11 = 10ms
Software Reset Delay
0 = No delay
1 = Software Reset is delayed by PWRSTATE_DLY
following the Software Reset command
Sets the device behaviour when starting up under USB
power, when USB_ILIM = 010b (100mA)
00 = Normal
01 = Soft-Start
10 = Only start if BATTVDD > 3.1V
11 = Only start if BATTVDD > 3.4V
In the 1X modes, if the battery voltage is less than the
selected threshold, then the device will enable trickle
charge mode instead of executing the start-up request.
The start-up request is delayed until the battery voltage
threshold has been met.
Indicates if the USB current limit has been reached
0 = Normal
1 = USB current limit
Sets the USB current limit
000 = 0mA (USB switch is open)
