DESCRIPTION
32 bits, and writes the result in rdest. The d value is an opcode modifier, must be in the range –128 and 126 inclusive,
and must be a multiple of 2. If the memory address computed by rsrc1 + d is not a multiple of 2, the result of

on the current setting of the bytesex bit in the PCSW.

the data cache status bits are updated if the addressed locations are cacheable. if the LSB of rguard is 0, rdest is not
