Pin description nomenclature:

•I

input only

•O

output only

• I/O bidirectional pin

• OD output only, open drain (requires external pull-up resistor to VDD).

The recommended pull-up resistance value for the open drain outputs is 2.7 k-ohm (this

is the recommended pull-up value suggested for PCI bus signals in the 5V signalling

environment).
