Function
Clear to Send
A low on the CTSn input enables the
respective transmitter.
Additionally, an interrupt may be issued if a
state transition occurs at the CTSn pin
(programmable feature).
If no ’Clear To Send’ function is required, the
CTSn inputs can be directly connected to V
Collision Data
In a bus configuration, the external serial bus
must be connected to the corresponding CxD
pin for collision detection.
A collision is detected whenever a logical ’1’ is
driven on the open drain TxD output but a
logical ’0’ is detected via CxD input.
Transmit Clock Gating
In clock mode 4 these pins are used as
Transmit Clock Gating signals.
