SYNTAX
FUNCTION
DESCRIPTION
result in rdest equal to rsrc1 arithmetically shifted left by n bits. The value of n must be between 0 and 31, inclusive.
Zeros are shifted into the LSBs of rdest while the MSBs shifted out of rsrc1 are lost.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
