1.6 Terminal Address
The Terminal Address of the RTR is programmed via five
input pins: RTA(4:0) and RTPTY. Asserting MRST latches
the RTR’s Terminal Address from pins RTA(4:0) and parity
bit RTPTY. The address and parity cannot change until the
next assertion of the MRST. The parity of the Terminal
Address is odd; input pin RTPTY is set to a logic state to
satisfy this requirement. A logic 1 on Status Register bit 12
indicates incorrect Terminal Address parity. An
example follows:
RTA(4:0) = 05 (hex) = 00101
RTPTY = 1 (hex) = 1
Sum of 1’s = 3 (odd), Status Register bit 12 = 0
RTA(4:0) = 04 (hex) = 00100
RTPTY = 0 (hex) = 0
Sum of 1’s = 1 (odd), Status Register bit 12 = 0
