8.0 Electrical Characteristics
8.2.2 NAND Tree Connections
During NAND tree testing, all outputs and bi-directional
pins will be tri-stated except BALE and RSTDRV pins. The
first input of the NAND chain is SA18. The NAND chain is
routed counter-clockwise around the chip (eg. SA18,
SA19, IRQ9, ...). TC is the intermediate output and RST-
test_in

DRV is the final output. BALE, PCIRSTX and IRQ7 are not
included in the NAND chain because they are required to
put the chip to NAND test mode. The NAND tree connec-
tion is as shown below.
