Hello.
I am trying ARM clock off method which is described in SPRUgm7d (P146) "10.6.2 ARM Clock OFF".
When dsp-core executes sequence 3(a) and 3(b), the arm can detect ARMCLKSTOPREQ interrupt.
But in the next sequence 3(c), PTSTAT.GOSTAT[0] can not be cleared.
It is anxious one, the user guide told that dsp must do the following.
1. The DSP stops all masters from accessing the ARM and ARM memory.
2. The DSP polls all masters for write-completion status (or wait n number of cycles, if the
transfer completion status is not implemented).
Because their directions are very vague, I can not understand what should I do.
- Does anyone have a example source code about ARM clock off sequence?
- Please let me know what should I do in the sequence 1 and sequence 2.
Best Regards,
BL.HSR-WZ
