Function
Transmit section DCC clock (TSDCLK)
This pin outputs a 216kHz clock.
TSDCLK0 corresponds to PORT0, while TSDCLK3
corresponds to PORT3.
Transmit section DCC (TSD) signals contains the serial
section data communications channel (D1, D2, and D3).
TSD0 corresponds to PORT0, while TSD3 corresponds to
PORT3.
Transmit line DCC clock (TLDCLK)
This pin outputs a 648kHz clock.
TLDCLK0 corresponds to PORT0, while TLDCLK3
corresponds to PORT3.
Transmit line DCC (TKD) signals contains the serial line
data communications channel (D4-D12).
TLD0 corresponds to PORT0, while TLD3 corresponds to
PORT3.
Receive section DCC clock (RSDCLK)
This pin outputs a 216kHz clock.
RSDCLK0 corresponds to PORT0, while RSDCLK 3
corresponds to PORT3.
Receive section DCC (RSD) signal contains the serial
section data communications channel (D1, D2, D3) extract
from the incoming stream.
RSD0 corresponds to PORT0, while RSD3 corresponds to
PORT3.
Receive line DCC clock (RLDCLK)
This pin outputs a 648kHz clock.
RLDCLK0 corresponds to PORT0, while RLDCLK 3
corresponds to PORT3.
Receive line DCC (RLD) signals contains the serial line data
communications channel (D4-D12) extract from the
incoming stream.
RLD0 corresponds to PORT0, while RLD3 corresponds to
PORT3.
