5 / 68 page ![]() MSC8152 Dual-Core Digital Signal Processor Data Sheet, Rev. 1 Freescale Semiconductor 5 1.2 Signal List By Ball Location Table 1 presents the signal list sorted by ball number. When designing a board, make sure that the power rail for each signal is appropriately considered. The specified power rail must be tied to the voltage level specified in this document if any of the related signal functions are used (active) Note: The information in Table 1 and Table 2 distinguishes among three concepts. First, the power pins are the balls of the device package used to supply specific power levels for different device subsystems (as opposed to signals). Second, the power rails are the electrical lines on the board that transfer power from the voltage regulators to the device. They are indicated here as the reference power rails for signal lines; therefore, the actual power inputs are listed as N/A with regard to the power rails. Third, symbols used in these tables are the names for the voltage levels (absolute, recommended, and so on) and not the power supplies themselves. Table 1.
