NAND Tree Testing
The PCnet-PCI controller provides a NAND tree test
mode to allow checking connectivity to the device on a
printed circuit board. The NAND tree is built on all PCI
bus signals.
NAND tree testing is enabled by asserting
RST. All PCI
bus signals will become inputs on the asserting of
RST.
The result of the NAND tree test can be observed on the
NOUT pin.
