The MASK2 register is used to mask all or any of the conditions in the corresponding REGSTATUS<7:0>
positions being indicated at the INT pin. Default is to mask all.

The ACKINT1 register is internally used to acknowledge any of the interrupts in the corresponding
CHGSTATUS<7:0> positions. When this is done, the acknowledged interrupt is no longer fed through to the INT
pin and so the INT pin becomes free to indicate the next pending interrupt. If none exists, then the INT pin goes
high, else it will remain low. A
1
at any position in ACKINT1 is automatically cleared when the corresponding
interrupt condition in CHGSTATUS is removed. The application processor should not normally need to access
the ACKINT1 register.

The CHGCONFIG register is used to configure the charger.
Bit 7 - AUA:
0 = If a voltage is present at AC or USB in the appropriate range for charging, and if V
CC
> UVLO, the
TPS65014 is forced into ON mode. The WAIT mode is disabled.
1 = If a voltage source at AC or USB is present, the WAIT mode is enabled, and the TPS65014 does not
automatically turn on the converters.
Bit 6 - Charger reset:
Clears all the timers in the charger and forces a restart of the charge algorithm.
0 / 1 = This bit must be set and then reset via the serial interface.
