PBA Example
If the PBA Number is “123456-003”
then word 08h = 1234h and word 09h = 5603h.
Through the course of hardware changes, the suffix field (byte 4) is incremented. The
purpose of this information is to enable customer support (or any user) to identify the
exact revision level of a product. The software device driver should not rely on this field
to identify the product or its capabilities.
