6.2.2. Isolation Protocol
A simple algorithm is used to isolate each Plug and Play card. This algorithm uses the signals on the ISA bus
and requires lock-step operation between the Plug and Play hardware and the isolation software.
State
Isolation
ID bit="1H"
SD[1:0]="01"
SD[1:0]="10"
Wait for next read from serial isolation register
Read all 72 bits

ID=0
other card ID=1
Leave SD [7:0]
in high impedance
Drive

After I/O read completes
fetch next ID bit from
