      AC/DC PARAMETERS
      These tables describe the AD and DC parameters
      of the PSD:
      DC Electrical Specification
      AC Timing Specification
      PLD Timing
      Combinatorial Timing
      Synchronous Clock Mode
      Asynchronous Clock Mode
      Input Macrocell Timing
      MCU Timing
      READ Timing
      WRITE Timing
      Peripheral Mode Timing
      Power-down and Reset Timing
      The following are issues concerning the parame-
      ters presented:
      In the DC specification the supply current is
      given for different modes of operation. Before
      calculating the total power consumption,
      determine the percentage of time that the PSD
      is in each mode. Also, the supply power is
      considerably different if the Turbo Bit is ’0.’
      The AC power component gives the PLD,
      Flash memory, and SRAM mA/MHz
      specification. Figures
      35
      and
      36
      show the PLD
      mA/MHz as a function of the number of
      Product Terms (PT) used.
      In the PLD timing parameters, add the
      required delay when Turbo Bit is ’0.’
