FUNCTION
DESCRIPTION
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 0xf310ffff
r10 = 0, r40 = 0xffff0000
r20 = 1, r40 = 0xffff0000
r50 = 0x88888888

Initial Values
operation computes the bitwise, logical NOT of the argument rsrc1 and writes the result into rdest.
operation optionally takes a guard, specified in rguard. If a guard is present, its LSB controls the
bitinv r30 → r60
IF r10 bitinv r40 → r70
IF r20 bitinv r40 → r100
bitinv r50 → r110
