(1) Open-drain driver with internal weak pull-up.
(2) PC_IRQ pins are three-stated if not assigned to a logical device.
(3) A pull-up or pull-down resistor may be required if EEPROM is used, because this pin is three-stated while EEPROM is read.
(4) An internal pull-up holds this pin deasserted until the EEPROM is read.
NOTE
The direction of some pins (input vs. output) depends on the flags. In order to prevent conflicts on pins that may be both inputs and
outputs, the AD1816 and AD1816A disable the output drivers for those pins while the flags are being read from the EEPROM, and
keep them disabled if the EEPROM data is invalid.
