transferred first. Because DSO changes state based on an internally-recognized rising edge of
DSCLK, DSDO cannot be used to indicate the start of a serial transfer. The development system
must count clock cycles in a given transfer. C1–C4 are described as follows:

.
• C1—First synchronization cycle for DSI (DSCLK is high).
• C2—Second synchronization cycle for DSI (DSCLK is high).
• C3—BDM state machine changes state depending upon DSI and whether the entire input
• C4—DSO changes to next value.
