Pin 120 (
RST) is the first input to the NAND tree. Pin 117
(
INTA) is the second input to the NAND tree, followed by
pin 121 (CLK). All other PCI bus signals follow, counter-
clockwise, with pin 57 (AD0) being the last. Pins labeled
NC and all power supply pins are not part of the NAND
tree. Table 9 shows the complete list of pins connected
to the NAND tree.

RST must be asserted low to start a NAND tree test se-
quence. Initially, all NAND tree inputs except
RST
should be driven high. This will result in a high output at
the NOUT pin. If the NAND tree inputs are driven from
high to low in the same order as they are connected to
build the NAND tree, NOUT will toggle every time an ad-
ditional input is driven low. NOUT will change to a
ZERO, when
INTA is driven low and all other NAND tree
inputs stay high. NOUT will toggle back to high, when
CLK is additionally driven low. The square wave will
continue until all NAND tree inputs are driven low.
NOUT will be high, when all NAND tree inputs are
driven low.
Note that some of the pins connected to the NAND tree
are outputs in normal mode of operation. They must not
be driven from an external source until the PCnet-PCI
controller is configured for NAND tree testing.
