DS2413: 1-Wire Dual Channel Addressable Switch
17 of 18
PIO ACCESS READ EXAMPLE
Read the state of the PIOs 3 times.
With only a single DS2413 connected to the bus master, the communication looks like this:
MASTER MODE
DATA (LSB FIRST)
COMMENTS
TX
(Reset)
Reset pulse
RX
(Presence)
Presence pulse
TX
CCh
Issue “Skip ROM” command
TX
F5h
Issue “PIO Access Read” command
RX
<3 data bytes>
Read 3 PIO samples
TX
(Reset)
Reset pulse
RX
(Presence)
Presence pulse
PIO ACCESS WRITE EXAMPLE
Set both PIOs to 0 and then set PIOA to 1. Both PIOs are pulled high to VCC or VPUP by a resistor.
With only a single DS2413 connected to the bus master, the communication looks like this:
MASTER MODE
DATA (LSB FIRST)

Issue “PIO Access Write” command
TX
FCh
Write new PIO output state
TX
03h
Write inverted new PIO output state
RX
AAh
Read confirmation byte
RX
F0h
Read new PIO pin status
TX
FDh

TX
02h
Write inverted new PIO output state
RX
AAh
Read confirmation byte
RX
C3h
Read new PIO pin status
TX

Reset pulse
RX
(Presence)
Presence pulse
Note: Usually, the PIO pin state and PIO Output Latch State are the same. To read from a PIO, the PIO Output
Latch must be 1. If the PIO pin is then pulled low by a switch or external circuitry, the output latch state and pin
state are different.
