(under subclass 223) Subject matter for control of execution or processing of instruction data peculiar to blocking and passing data elements contained within memory words or processor registers.
(1) Note. This subclass provides for control of execution of instruction data which is peculiar to masking. Generic masking of digital words in a digital data processing system is classified elsewhere.
(2) Note. Masking is a generic technique for stripping, passing, eliminating, or blocking a part of a digital word. Masking used as a subcombination to an overall combination such as, for example, to enable or disable interrupts or to enable or disable a status line is classified elsewhere.
