Function
a LOW-level on MR only affects the shift registers
empty shift register loaded into storage register
shift register clear; parallel outputs in high-impedance OFF-state
logic HIGH-level shifted into shift register stage 0. Contents of all
shift register stages shifted through, e.g. previous state of stage 6
(internal Q6S) appears on the serial output (Q7S).
contents of shift register stages (internal QnS) are transferred to
the storage register and parallel output stages
contents of shift register shifted through; previous contents of the
shift register is transferred to the storage register and the parallel
output stages
