features. The OCI provides run control, memory and register visibility, complex break-
points, and trace history features.
The OCI employs all of the functions of the ZDI as described in the Zilog Debug Interface
section that starts on page 162. It also adds the following debug features:
•
•
•
•
•
There are four sections to the OCI:
1. JTAG interface
2. ZDI debug control
3. Trace buffer memory
4. Complex triggers
OCI features clock initialization circuitry so that external debug hardware can be detected
during power-up. The external debugger must drive the OCI clock pin (TCK) Low at least
two system clock cycles prior to the end of the RESET to activate the OCI block. If TCK
is High at the end of the RESET, the OCI block shuts down so that it does not draw power
in normal product operation. When the OCI is shut down, ZDI is enabled directly and can

Control via a 4-pin Joint Test Action Group (JTAG)-standard port that conforms to the
IEEE Standard 1149.1 (Test Access Port and Boundary Scan Architecture)
Complex break point trigger functions
