selectable by OCD Registers, minimizing the chance that the AUX port will need to be shared
with an application.
Table 39-5.
In order to use this module, other parts of the system must be configured correctly, as described
below.
The OCD clock operates independently of the CPU clock. If enabled in the Power Manager, the
OCD clock (CLK_OCD) will continue running even if the CPU enters a sleep mode that disables
the CPU clock.
The OCD has a clock (CLK_OCD) running synchronously with the CPU clock. This clock is gen-
erated by the Power Manager. The clock is enabled at reset, and can be disabled by writing to
the Power Manager.
The OCD system interrupt request lines are connected to the interrupt controller. Using the OCD
interrupts requires the interrupt controller to be programmed first.
