NAND Tree Testing
The FW323 can be placed into a NAND tree mode of operation to enable board-level production testing. The
NAND tree mode is designed to allow board-level contact testing of the digital pins of the FW323. To place the
FW323 into NAND tree mode, pins 10 (TEST0), 7 (TEST1), and 124 (PTEST) should all be forced high. (Note: In
normal mode, these inputs are forced low.) The output for NAND tree is pin 6. No clocks are required for NAND tree
testing. When NAND tree is enabled, the NAND tree logic follows the signal ordering in the following table.
To run the test, force all of the inputs in the table below high. At this point, the NAND tree output should be verified
to be high. In the order listed below, force each input low, while keeping previously tested inputs low. After each
input is forced low, the NAND tree output should be verified, and the correct value should be the opposite of the
previous value. Therefore, after forcing the first input low, the NAND tree output should be low, after forcing the sec-
ond input low (and keeping the first input low), NAND tree output should be high, etc.
