14.2 Two-pin external interface
14.2.1 Basic transmission packet
10-bit packet transmission via two-wire interface.
1 packet consists of 8-bit data, 1-bit parity and 1-bit acknowledge.
Even parity for 8-bit transmit data.
Receiver gives acknowledge bit by pulling the data line low when 8-bit transmit data and parity bit
has no error.
When transmitter receives no acknowledge bit from the receiver, error process is done by
transmitter.
When acknowledge error is generated, host PC issues a stop condition and re-transmits the
command.
Background debugger command is composed of a bundle of packets.
Each packet starts with a start condition and ends with a stop condition.
