240-Pin MQFP Pin Assignments

Table 14 lists the pin number, pin name, and pin type for the 240-pin CS98200 package. The primary

function and pin direction is shown for all signal pins. For some signal pins, a secondary function

(or functions) and direction are also shown. For pins having more than one function, the primary

function is chosen when the chip is reset.
