SYNTAX
FUNCTION
DESCRIPTION
result in rdest equal to rsrc1 rotated left by n bits. The value of n must be between 0 and 31, inclusive. The most-
significant n bits of rsrc1 appear as the least-significant n bits in rdest.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
