PIN MUX ING IN T HE AD1816 AND AD1816A
Some AD1816 and AD1816A options are mutually exclusive because there are a limited number of pins on the device to support
them all. T he tables below map functions to pin, and show how the flags must be set to assign functions to pins. For each pin, the
first function listed is the default; that function is used if the EEPROM is absent or invalid.

(1) IRQ pins are three-stated if not assigned to a logical device.
(2) A pull-up or pull-down resistor may be required if EEPROM is used, because this pin is three-stated while EEPROM is read.
