Bitwise logical NOT
SYNTAX
FUNCTION
DESCRIPTION
modification of the destination register. If the LSB of r guard is 1, r dest is written; otherwise, r dest is not changed.
EXAMPLES
r30 = 0xf310ffff
r10 = 0, r40 = 0xffff0000
r20 = 1, r40 = 0xffff0000
r50 = 0x88888888

Initial Values
~r src1
operation computes the bitwise, logical NOT of the argument r src1 and writes the result into r dest .
operation optionally takes a guard, specified in r guard . If a guard is present, its LSB controls the
