pullup resistor from IRQ/SEG9 to a voltage no greater
than 5.5V when configuring IRQ/SEG9 as an interrupt
or logic output.
INPUT1 and INPUT2 can be individually configured as
either general-purpose logic inputs or as keyscan
inputs. In either mode, the input structure is the same—
CMOS logic inputs with internal pullup resistors. The

ADDRESS
pullups are always enabled, even in shutdown. Ensure
these inputs are either close to V+ or open circuit for
minimum shutdown supply current. If both INPUT1 and
INPUT2 are assigned to keyscan, then eight keys can
be debounced. If only INPUT1 or INPUT2 is assigned
to keyscan, then only four keys can be debounced.
