Electrical connection of TRx+ and TRx- (x = A, B, C or D) pins depends on the selected electrical style. When the electrical style is differential (LVDS, RS485, DTTL), the signal has to be connected between the TRx+ and TRx- (x = A, B, C or D) pins. When the electrical style is single-ended (TTL, TTLPD, 12V), the signal has to be connected between the TRx+ and the GND (x = A, B, C or D) pins.

See I/O Operation for the operation of I/O lines.
