6 IF inputs; no digital output (after POR)
1
4 IF inputs; 2 digital outputs
Note
1. Two IF inputs (IN-5 and IN-6; pins 7 and 8) can be used as digital output instead. If no more than four IF inputs are
needed, two external functions can be controlled via the I²C-bus this way. The level at these pins is controlled by
bits IL2 (i7) and IR2 (i4); see Tables 7 and 8.
