APPLICATION INFORMATION
NAND tree test
All bi-directional pins are tri-stated for input mode during the NAND Tree test except SIDO. All inputs except
TEST should be forced low then forced high, one signal at a time, in the order listed below. The TEST pin is the
last signal in the chain and is forced high then low. The NAND result is driven on the SIDO output pin as shown
in the timing diagram in Figure 5.
