AM2434: PRU Question: How many core clock cycles for logical instructions?

Tool/software:

I am programming in assembly for the PRU0/PRU1 cores on the AM243x hardware.
I was wondering, how many core clock cycles do the logical shift operations (lsl / lsr) consume?

For example:

; Left-Shift Operation
lsl     r2, r2, 10

; Right-Shift Operation
lsr     r2, r2, 10

These commands perform left/right bit shift on R2 of 10bit places.
Does each operation take 10 core clock cycles, or just one?
