Bits 15 - Bit 8 – RFU; Reserved for future use. These bits will always read '0' and writing to them will have no affect.
Bit 7- EVSD-EVENT with Shutdown action.
‘0’ - (default) The EVENT output freezes in its current state when entering shutdown. Upon exiting shutdown, the EVENT output remains in the
‘1’ The EVENT output is deasserted (not driven) when entering shutdown and remains deasserted upon exit from shutdown until the next thermal
