Item
The terms ‘set’, ‘active’, and ‘asserted’ are synonymous.
They do not necessarily infer logic one.
(For example, an active-low signal can be set to logic zero.)
The terms ‘cleared’, ‘inactive’, and ‘de-asserted’ are synonymous.
They do not necessarily infer logic zero.
In reference to the ICS1893CY-10, the term ‘Twisted-Pair Receiver’ refers to
the set of Twisted-Pair Receive output pins (TP_RXP and TP_RXN).
In reference to the ICS1893CY-10, the term ‘Twisted-Pair Transmitter’ refers to
the set of Twisted-Pair Transmit output pins (TP_TXP and TP_TXN).

When referring to signals, the terms:
– ‘FALSE’, ‘low’, or ‘zero’ represent signals that are logic zero.
– ‘TRUE’, ‘high’, or ‘one’ represent signals that are logic one.
Chapter 9, “DC and AC Operating Conditions”
specifications for ‘logic zero’ and ‘logic one’ signals.
In this data sheet, code group names are referred to as ‘symbols’ and they
are shown between '/' (slashes). For example, the symbol /J/ represents
the first half of the Start-of-Stream Delimiter (SSD1).
Symbol sequences are shown in succession. For example, /I/J/K/
represents an IDLE followed by the SSD.
