(1)

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal.

(2)

Specifies the operating I/O supply voltage for each signal. See Section 5.3, Power Supplies for more detail.

(3)

PD = pull-down, PU = pull-up. (To pull up a signal to the opposite supply rail, a 1 k

Ω resistor should be used.)

The DM355 provides Pulse Width Modulator (PWM) interface.
