11.2Memory Organization

Several of the serial ports contain more than one serial engine. Each individual engine is self-contained (no shared logic or registers) and implements a separate serial protocol. Serial ports 1, 2, and 4 each contain two separate serial engines, totalling eight separate serial engines within all five serial ports. Each of the eight serial engines, including the peripheral pin controller (PPC), has been allocated a separate 64 Kbyte block on-chip memory space in which its registers reside. Although the register width of individual units varies, each register is right justified on word boundaries. All register accesses via the CPU must be performed using word reads and writes. This chapter includes a summary of individual peripheral registers. See Appendix A, “Register Summary” for a complete summary of all on-chip registers.
