Runtime Counter
The OCD contains a 16-bit runtime counter. It counts system clock cycles between break-
points. The counter starts counting when the OCD leaves DEBUG Mode and stops count-
ing when it enters DEBUG Mode again or when it reaches the maximum count of
The host communicates to the On-Chip Debugger by sending OCD commands using the
DBG interface. During normal operation, only a subset of the OCD commands are avail-
able. In DEBUG Mode, all OCD commands become available unless the user code and
control registers are protected by programming the Flash read protect option bit (FRP).
The FRP prevents the code in memory from being read out of the Z8 Encore! F0830 Series
products. When this option is enabled, several of the OCD commands are disabled.
Table 95 summarizes the On-Chip Debugger commands. This table indicates the com-
mands that operate when the device is not in DEBUG Mode (normal operation) and the
commands that are disabled by programming the FRP.
