SYNTAX
FUNCTION
DESCRIPTION
result in rdest that is equal to rsrc1 logically shifted right by n bits. The value of n must be between 0 and 31, inclusive.
Zeros fill vacated bits from the left.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
EXAMPLES
r30 = 0x7008000f
r30 = 0x7008000f
r10 = 0, r30 = 0x7008000f
r20 = 1, r30 = 0x7008000f
r40 = 0x80030007
r30 = 0x7008000f
r40 = 0x80030007
