DS2406

After the Channel Control bytes have been transmitted the bus master receives the Channel Info byte
(Figure 9). This byte indicates the status of the channel flip-flops, the PIO pins, the activity latches as
well as the availability of channel B and external power supply. To be able to read from a PIO channel,
the output transistor needs to be non-conducting, which is equivalent to a 1 for the channel flip-flop.
Reading 0 for both the channel flip-flop and the sensed level indicates that the output transistor of the PIO
is pulling the node low. For the Channel Info byte PIO A and B are sampled at the same time, as in the
synchronous mode. If channel B is available, bit 6 of the Channel Info Byte reads 1. For 1-channel
versions of the DS2406, the PIO B sensed level, channel flip-flop value, and activity latch value should
be ignored. Without an external supply, the supply indication bit (bit 7) reads 0. As long as the voltage
applied to the V
CC
pin is high enough to operate the device this bit will read 1.
