    DETAILED OPERATION
    As shown in
    Figure 5., page 14
    , the PSD consists
    of six major types of functional blocks:
    Memory Blocks
    PLD Blocks
    MCU Bus Interface
    I/O Ports
    Power Management Unit (PMU)
    JTAG Interface
    The functions of each block are described in the
    following sections. Many of the blocks perform
    multiple functions, and are user configurable.
    Memory Blocks
    The PSD has the following memory blocks:
    Primary Flash memory
    Optional Secondary Flash memory
    Optional SRAM
    The Memory Select signals for these blocks origi-
    nate from the Decode PLD (DPLD) and are user-
    defined in PSDsoft Express.
