The Low-Voltage BMS module's power interface subsystem also has GPOs via the
pi_gpo but these should not be configured for general usage.

7.7.3. General Purpose Digital Inputs

The most commonly used General Purpose Digital Input functions are:
▪
Clear faults: Hardware input to clear any latched fault conditions
▪
Connect request: Request to connect the battery stack to the DC bus
▪
Auxiliary contactor feedback: Provides feedback to compare an auxiliary contactor state with
current contactor state.
The Low-Voltage BMS has a dedicated input for clearing faults. Refer to

inputs do not have to be used.
General Purpose Digital Input functions are assigned through the following configuration registers.
The index n is the zero-based index of the General Purpose Digital Input hardware pin.

▪
When set to 1, the state of the input pin is propagated to the destination register address
sc_gpi[n].inverted
▪
When set to 0, GPI input value is 1 if hardware GPI is asserted
▪
When set to 1, GPI input value is 0 if hardware GPI is asserted
