14.2 Two-Pin External Interface
14.2.1 Basic Transmission Packet
•
10-bit packet transmission using two-pin interface.
•
1-packet consists of 8-bit data, 1-bit parity and 1-bit acknowledge.
•
Parity is even of ‘1’ for 8-bit data in transmitter.
•
Receiver generates acknowledge bit as ‘0’ when transmission for 8-bit data and its parity has no error.
•
When transmitter has no acknowledge (Acknowledge bit is ‘1’ at tenth clock), error process is executed in
transmitter.
•
When acknowledge error is generated, host PC makes stop condition and transmits command which has
error again.
•
Background debugger command is composed of a bundle of packet.
•
Star condition and stop condition notify the start and the stop of background debugger command respectively.
