Function
Request to Send Channel A
The function of this pin depends on the settings of
bits RTS, FRTS in register
In bus configuration, RTS can be programmed to:
– go low during the actual transmission of a
– go low during reception of a data frame.
– stay always high (RTS disabled).
Clear to Send Channel A
A low on the CTSA input enables the transmitter.
Additionally, an interrupt may be issued if a state
transition occurs at the CTSA pin (programmable
feature).
If no ’Clear To Send’ function is required, a pull-
down resistor to V
Collision Data Channel A
In a bus configuration, the external serial bus
must be connected to the corresponding CxDA
pin for collision detection.
A collision is detected whenever a logical ’1’ is
driven on the open drain TxDA output but a
logical ’0’ is detected via CxDA input.
Transmit Clock Gating Channel A (cm 4)
In clock mode 4 these pins are used as Transmit
Clock Gating signals.
If no clock gating function is required, a pull-up
resistor to V
Octet Sync Transmit Channel A (cm 5b)
When the SCC is in the time-slot oriented clock
mode with octet-alignment (clock mode 5b), a
synchronization pulse on this input pin aligns
transmit octets.
frame shifted by one clock period, excluding
collision bits.
