Input
Serial data output pin of the real-time debugger
Serial data input pin of the real-time debugger
RTDCLK
Clock input
Input
Serial data transmit/receive clock input pin of the real-time debugger
RTDACK
Acknowledge
Output
This pin outputs a low pulse synchronously with the real-time debugger’s
first clock of serial data output word. The low pulse width indicates the
type of the command/data the realtime debugger has received.
