Notes: 1. ATN is a normal transceiver channel that functions additionally as an internal direction control or talk enable

for EOI whenever the DC and TE inputs are in the same state.

2. Direction of data transmittion is from the terminal side to the bus side and the direction of data receiving is

from the bus side to the terminal side. Data transfer is noninverting in both directions.
