i.MX6 Reference Manual describes in table 38-25 "DC template's commands description" the N parameter of the BMA instruction as
The N operand defines the N-number of routine's repetitions.
What is "routine" in this context? E.g. have I to use this operation in a way like
0: HMA(4) 1: HMA1(2) 2: HLG(23) 3: BMA(LF=0, AF=0, N=42, SYNC=0) 4: HLG(STOP=1, 0) /* noop */
to execute HLG(23) 42 times? What would be the meaning of the STOP bit in BMA in this case?
Or, have I to write it like
0: HMA(3) 1: HMA1(4) 2: BMA(LF=0, AF=0, N=42, SYNC=0) 3: HLG(STOP=1, 0) 4: HLG(STOP=1, 23)
Is it possible to nest BMA instructions in this case (use LF=0 for outer and LF=1 for inner loop)? Have I to restore HMA/HMA1 after leaving the internal loop?
