1. Data is read into the shift register in synchronization with a rising edge of the clock, with the higher data being shifted
sequentially on a first-come highest-bit basis.
2. When the strobe is low, data is shifted sequentially on the sift register in synchronization with the clock. Data on the
latch circuit will not change.
3. When the strobe goes high, the latched data whose address is represented by the highest six bits of the shift register is
updated. Latched data is set when the least significant bit is 1, and reset when the bit is 0.
4. Referring to 3 above, if the address is h00 (the highest six bits of the shift register are all 0s), the latch circuit is cleared
(all reset) regardless of the data content.
5. At power-on (VCC ON), the latch circuit is cleared (by power-ON reset).
