control conditions. A ‘1’ sets charge control.
depending on the programming of each
individual pin as an input or output via the
GPIODirection register:
Input:
Output: 1 = LED Output
conditional I/O in GPIOConfig is an input or
an output. A ‘1’ bit means output, ‘0’ means
input.
should be used in the state-of-charge
display when the "switch" is pushed. A ‘1’
sets the GPIO to be state-of-charge display.
programmed here. When an I/O is
triggered, it can be programmed here to go
either high or low, and the opposite state
will be the default (not triggered). Set the
appropriate bit to ‘1’ for active being high
level (LED on), and ‘0’ for active being low
level (LED off).
