BIT NAME DESCRIPTION 6:0 Reserved Read Only. A read returns 0 7Valid A high level on this software-controlled bit can be used to indicate that a valid configuration cycle has occurred. The control software must take care to set this bit at the appropriate times. Set to zero after power up. This bit has no effect on any other hardware in the chip.
