16.12.6 Registers 90–AFh Voltage Limit Registers
FFh as the high limit acts as a mask for that voltage sensor and so prevents this channel from being able to set the associated
error status bit in the B_ or H_ Error Status registers, for both high and low limit errors.
If a voltage input either exceeds the value set in the voltage high limit register or falls below the value set in the voltage low limit
register, the corresponding bit is set automatically by the LM96194 in the B_ and H_Error Status registers.
