Default 0000h

The BDI Status Register (Index 7Ah) reflects the state of all possible events. If a bit is ‘0’, the corresponding event has

not occurred or has already been handled by the driver. If a bit is ‘1’, the corresponding event has occurred and has not

been handled by the driver yet. The BDI bit in input slot 12 is a logic OR of all bits in this register ANDed with their cor-

responding bit in the BDI Config Register (Index 6Eh, Address 0Ch). After handling an event, the driver should clear it

by writing a ‘0’ to the corresponding bit of this register.
