Data Logging

(DMA_CNTRL). EVT_CNTRL is described in Table 7−5 (page 7-26),
and DMA_CNTRL is described in Table 7−4 (page 7-25).
Note:
The application must not read from the end address of the buffer during the
data logging operation. When the end address appears on the address bus,
the C28x ends the transfer.
4) Execute the EDIS instruction to disable access to emulation registers.
See Table 7−4 and Table 7−5 on the following pages for descriptions of the
registers associated with data logging.
