DS2407
012099 16/31
available, bit 6 of the Channel Info Byte reads 1. For
1–channel versions of the DS2407, the PIO B sensed
level, channel flip–flop value, and activity latch value
should be ignored. Without an external supply, the sup-
ply 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.
