Field Name Bits Default Description
PVS_FC_LOOP_INIT_VAL_0 7:0 0x0 This field stores the automatic loop index register init
value. This is an 8-bit unsigned value 0-255. This field
is only used if the corresponding control flow
instruction is a loop.
PVS_FC_LOOP_STEP_VAL_0 15:8 0x0 This field stores the automatic loop index register step
value. This is an 8-bit 2`s comp signed value -128-127.
This field is only used if the corresponding control
flow instruction is a loop.
PVS_FC_LOOP_REPEAT_NO_FLI_0 31 0x0 When this field is set, the automatic loop index register
init value is not used at loop activation. The intial loop
index is inherited from outer loop. The loop index
register step value is used at the end of each loop
iteration ; after loop completion, the outer loop index
register is restored
