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 VCC pin is high enough to operate the device this bit will read 1.
