The WAIT polarity bit indicates whether an asserted WAIT output should be HIGH or
LOW. This bit will determine whether the WAIT signal requires a pull-up or pull-down
resistor to maintain the de-asserted state.
The latency counter bits determine how many clocks occur between the beginning of a
READ or WRITE operation and the first data value transferred. Only latency code two
(three clocks) or latency code three (four clocks) is allowed (see Table 5 and Figure 21)
