The LSL Command left shifts the input in register R3 by a shift amount specified by R12(2)
Shifting by k bits means a multiplication of 2^k.
Value in R3 = 2B78DFE0 in hex = 729341920 in decimal
729341920 * (2^2) = 729341920 * 4 = 2917367680 = 0xADE37F80
Hence the only updated value is in register R3 = 0xADE37F80
No change in any other value.
P.S. Please give a thumbs up if my answer could be of help to you!
