Note: Each bit of this register will generate an interrupt at pin INT if activated (internally
set to '1'). The bits and the pin INT are cleared after read. Setting of these bits by
activated source can be inhibited by masking in register IRMASK.
STATUS[6:0] (Addr.: 6EH): Status
Bits are reset when the interrupt source is no longer valid
