I/O Buffer Enable (IOBE)

IOBE is the I/O Buffer Enable for the INT and RDY signals. At startup, INT and RDY outputs are High-Z. Bits 6 and 7 become valid after IOBE is set to "1". IOBE can be reset by a Cold Reset or by writing "0" to bit 5 of System Configuration1 Register.

I/O Buffer Enable Information[5]

Item	Definition	Description
IOBE	I/O Buffer Enable for INT and	0 = disable (default)
IOBE	RDY signals	1 = enable
	RDY signals	1 = enable

RDY Configuration (RDY conf)
RDY Configuration Information[4]

Item	Definition	Description
RDY conf	RDY configuration	0=active with valid data(default)
RDY conf	RDY configuration	1=active one clock before valid data
		1=active one clock before valid data
