FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION

is in effect a parallel path for the power key.
has the global reset feature enabled by default. The 13892B version has the global reset feature disabled by default, but can be
enabled by setting the SPI bit GLBRSTENB = 0. The global reset feature powers down the part, disables the charger, resets the
SPI registers to their default value and then powers back on. To enable a global reset the PWRON3 pin needs to be pulled low
for greater than 12 seconds and then pulled back high. If the PWRON3 pin is held low for less than 12 seconds the pin will act
as a normal PWRON pin.
PUMS1 AND PUMS2
Power Up Mode Select pins (PUMS1 and PUMS2) are used to configure the start-up characteristics of the regulators. Supply
enabling and output level options are selected by hardworking the PUMS pins for the desired configuration.
