6.1 Pin Assignments
Table 6 lists the pin number, pin name and pin type
for the 208 pin CS98000 package. The primary
function and pin direction is shown for all signal
pins. For some signal pins, a secondary function
and direction are also shown. For pins having more
than one function, the primary function is chosen
when the chip is reset.
