      Architectural
      Overview
      (cont.)
      4.5 ISP via JTAG Port
      In-System Programming can be performed through the JTAG pins on Port E. This serial
      interface allows complete programming of the entire PSD4000 device. A blank device can
      be completely programmed. The JTAG signals (TMS, TCK, TSTAT, TERR, TDI, TDO) can
      be multiplexed with other functions on Port E. Table 3 indicates the JTAG signals pin
      assignments.
      4.6 In-System Programming (ISP)
      Using the JTAG signals on Port E, the entire PSD4000 (memory, logic, configuration)
      device can be programmed or erased without the use of the microcontroller.

      4.7 In-Application re-Programming (IAP)
      The main Flash memory can also be programmed in-system by the microcontroller
      executing the programming algorithms out of the secondary Flash memory, or SRAM.
      Since this is a sizable separate block, the application can also continue to operate. The
      secondary Flash boot memory can be programmed the same way by executing out of the
      main Flash memory. Table 4 indicates which programming methods can program different
      functional blocks of the PSD4000.

      Table 4. Methods of Programming Different Functional Blocks of the PSD4000
      4.8 Page Register
      The eight-bit Page Register expands the address range of the microcontroller by up to
      256 times.The paged address can be used as part of the address space to access
      external memory and peripherals or internal memory and I/O. The Page Register can also
      be used to change the address mapping of blocks of Flash memory into different memory
      spaces for IAP.
      4.9 Power Management Unit
      The Power Management Unit (PMU) in the PSD4000 gives the user control of the
      power consumption on selected functional blocks based on system requirements. The
      PMU includes an Automatic Power Down unit (APD) that will turn off device functions due
      to microcontroller inactivity. The APD unit has a Power Down Mode that helps reduce
      power consumption.
      The PSD4000 also has some bits that are configured at run-time by the MCU to reduce
      power consumption of the GPLD. The turbo bit in the PMMR0 register can be turned off
      and the GPLD will latch its outputs and go to standby until the next transition on its inputs.
      Additionally, bits in the PMMR2 register can be set by the MCU to block signals from
      entering the GPLD to reduce power consumption. See section 9.5.
