In this manual, assertion and negation are used to specify forcing a signal to a particular state. In particular, assertion and assert refer to a signal that is active or true; negation and negate indicate a signal that is inactive or false. These terms are used independently of the voltage level (high or low) that they represent. Data and address sizes are defined as follows: ❏ A byte is eight bits, numbered 0 through 7, with bit 0 being the least significant. ❏ A word is 16 bits, numbere
