3 / 10 page Functional Description The Transmit/Receive (T/R) input determines the direction of the data flow through the bidirectional transceivers. Transmit (active HIGH) enables data from the A port to the B port; Re- ceive (active LOW) enables data from the B port to the A port. The Output Enable (OE) input disables the parity and ERROR outputs and both the A and B ports by placing them in a HIGH-Z condition when the Output Enable input is HIGH. When transmitting (T/R HIGH), the parity generator detects whether an even or odd number of bits on the A port are HIGH and compares these with the condition of the parity se- lect (ODD/EVEN). If the Parity Select is HIGH and an even number of A inputs are HIGH, the Parity output is HIGH. In receiving mode (T/R LOW), the parity select and number of HIGH inputs on port B are compared to the condition of the Parity input. If an even number of bits on the B port are HIGH, the parity select is HIGH, and the PARITY input is HIGH, then ERROR will be HIGH to indicate no error. If an odd number of bits on the B port are HIGH, the parity select is HIGH, and the PARITY input is HIGH, the ERROR will be LOW indicating an error. www.national.com 3 |
