Freescale Semiconductor
Ownership Trace Register (OTR). The operating system writes the ID for the current task/process in the
OTR. The UBA is read and written to by the external development tool.
NOTE
It is recommended that the UBA only be modified while system reset is
asserted or in debug mode. Caution should be taken when modifying the
UBA when system reset is negated.
11.10.3.5 Read/Write Access Control/Status (RWCS)
The Read Write Access Control/Status Register provides control for Read/Write Access. Read/Write
access provides DMA-like access to Advanced High-performance Bus (AHB) memory mapped resources
when the processor is halted or during runtime. The RWCS Register also provides Read/Write Access
Status information per Table 11-26.
Offset see Table 11-21
