User and privilege mode (read):
0
Accesses inside the trace regions are traced.
1
Accesses outside the trace regions are traced.
Privilege mode (write):
0
Allow tracing of accesses inside the regions set in RTPRAMxREGy

3-0
ON/OFF
ON/Off switch.
User and privilege mode (read):
Ah
Tracing of data is enabled.
All Others
Tracing of data is disabled.
Privilege mode (write):
Ah
Enable Tracing of data. If there is any previous captured data remaining, it will be shifted out.
All Others
Disable tracing of data. If there is still data left in the shift register, it will be shifted out before
disabling the shift operations. The data captured in the FIFO remains there until the ON/OFF
bits are set to Ah.
NOTE:
It is recommended to write 5h to disable the module to prevent a soft error from
enabling the module inadvertently by a single bit flip.
