8.2.12 Internal Status (Status) and Interrupt Mask (Mask)
DS682F1
Default =
The Status register indicates a variety of conditions within the chip. Writing a '1' to a Status register bit will clear
that bit if the condition that set it has been removed. Writing a '0' to any bit has no effect.
The Mask register is used to control the activation of the INT pin. Placing a logic '1' to a Mask register bit will
allow the corresponding Status register bit to activate the INT pin when set.
