If it hits an IRW, that is followed, possibly in a chain of IRWs until a data word is found.
22.
Data words start in the middle of the high phase of the clock, and the most significant bit is transmitted first.
23.
Instead of processing all of a long word on one integrated circuit, multiple circuits in parallel processed subsets of each data word.
24.
This is the modular sum of the values taken by the simple checksum as each block of the data word is added to it.
25.
It was a major revelation to designers of this period to realize that the data word should be a multiple of the character size.
26.
This is the number of clock cycles allowed for internal operations between a read command and the first data word appearing on the data bus.
27.
For example, the elements might be computer data words, where the first combining operation is exclusive or and the second is logical conjunction.
28.
At the end of the data word, the modulus operator is applied and the two values are combined to form the Fletcher checksum value.
29.
Once a complete data word has been shifted into the circuit under test, it can be latched into place so it drives external signals.
30.
An absolute encoder has multiple code rings with various binary weightings which provide a data word representing the absolute position of the encoder within one revolution.
